subheadings for research paper

Headings identify the content within sections of a paper.

Make your headings descriptive and concise. Headings that are well formatted and clearly worded aid both visual and nonvisual readers of all abilities.

Levels of heading

There are five levels of heading in APA Style. Level 1 is the highest or main level of heading, Level 2 is a subheading of Level 1, Level 3 is a subheading of Level 2, and so on through Levels 4 and 5.

The number of headings to use in a paper depends on the length and complexity of the work.

• If only one level of heading is needed, use Level 1.
• If two levels of heading are needed, use Levels 1 and 2.
• If three levels of heading are needed, use Levels 1, 2, and 3 (and so on).

Use only the number of headings necessary to differentiate distinct sections in your paper; short student papers may not require any headings. Furthermore, avoid these common errors related to headings:

• Avoid having only one subsection heading within a section, just like in an outline.
• Do not label headings with numbers or letters.
• Double-space headings; do not switch to single spacing within headings.
• Do not add blank lines above or below headings, even if a heading falls at the end of a page.

Headings are covered in the seventh edition APA Style manuals in the Publication Manual Sections 2.26 and 2.27 and the Concise Guide Sections 1.25 and 1.26

Format of headings

The following table demonstrates how to format headings in APA Style.

Note. In title case, most words are capitalized .

Headings in the introduction

Because the first paragraphs of a paper are understood to be introductory, the heading “Introduction” is not needed. Do not begin a paper with an “Introduction” heading; the paper title at the top of the first page of text acts as a de facto Level 1 heading.

It is possible (but not required) to use headings within the introduction. For subsections within the introduction, use Level 2 headings for the first level of subsection, Level 3 for subsections of any Level 2 headings, and so on. After the introduction (regardless of whether it includes headings), use a Level 1 heading for the next main section of the paper (e.g., Method).

Creating accessible headings

Writers who use APA Style may use the automatic headings function of their word-processing program to create headings. This not only simplifies the task of formatting headings but also ensures that headings are coded appropriately in any electronic version of the paper, which aids readers who use navigation tools and assistive technologies such as screen readers. 

Here are some tips on how to create headings in some common word-processing programs:

• If you use Academic Writer to write your APA Style papers, the headings menu in the Writing Center will format headings for you in 7th edition APA Style.
• Follow these headings directions from Microsoft to customize the heading formats for your future use.
• To apply Level 4 and 5 headings (which are inline headings, meaning the heading appears on the same line as paragraph text), first type the heading and a few words of the text that follows. Then highlight the text that you want to be your heading and select the appropriate heading level from the Styles menu. Only the highlighted text will be formatted as the Level 4 or 5 heading.

How do I style headings and subheadings in a research paper?

Headings and subheadings can help organize and structure your writing. In general, longer and more complex works warrant more of them than shorter ones. Avoid overusing headings in short projects; they should never be used to compensate for poor structure or to explain an underdeveloped idea.

When headings are called for in your writing project, observe the basic guidelines below.

The paper or chapter title is the first level of heading, and it must be the most prominent.

Headings should be styled in descending order of prominence. After the first level, the other headings are subheadings—that is, they are subordinate. Font styling and size are used to signal prominence. In general, a boldface, larger font indicates prominence; a smaller font, italics, and lack of bold can be used to signal subordination. For readability, don’t go overboard: avoid using all capital letters for headings (in some cases, small capitals may be acceptable):

Heading Level 1

Heading Level 2

Heading Level 3

Note that word-processing software often has built-in heading styles.

Consistency

Consistency in the styling of headings and subheadings is key to signaling to readers the structure of a research project. That is, each level 1 heading should appear in the same style and size, as should each level 2 heading, and so on. Generally avoid numbers and letters to designate heads unless you are working in a discipline where doing so is conventional. Note that a heading labeled “1” requires a subsequent heading labeled “2,” and a heading labeled “a” requires a subsequent heading labeled “b.” 

In a project that is not professionally designed and published, headings should be flush with the left margin, to avoid confusion with block quotations. (The exception is the paper or chapter title, which is centered in MLA style.)

For readability, it is helpful to include a line space above and below a heading, as shown in this post.

No internal heading level should have only one instance. For example, if you have one level 1 heading, you need to have a second level 1 heading. (The exceptions are the paper or chapter title and the headings for notes and the list of works cited.) You should also generally have text under each heading.

Capitalization

Capitalize headings like the titles of works, as explained in section 1.5 of the MLA Handbook .

The shorter, the better.

Formatting Research Paper Headings and Subheadings

Different style guides have different rules regarding the formatting of headings and subheadings in a paper, but what information you should actually put into your subheadings is a different question and often up to personal taste. Here we quickly summarize general guidelines, different approaches, and what not to do when choosing headings for a research paper.

Does it matter how I name my sections and subsections?

The main sections of a research paper have general headers and are often journal-specific, but some (e.g., the methods and discussion section) can really benefit from subsections with clear and informative headers. The things to keep in mind are thus the general style your paper is supposed to follow (e.g., APA, MLA), the specific guidelines the journal you want to submit to lists in their author instructions , and your personal style (e.g., how much information you want the reader to get from just reading your subsection headers).

Style Guides: Research Paper Heading and Subheading Format

Headers identify the content within the different sections of your paper and should be as descriptive and concise as possible. That is why the main sections of research articles always have the same or very similar headers ( Introduction, Methods, Results, Discussion ), with no or only small differences between journals. However, you also need to divide the content of some of these sections (e.g., the method section) into smaller subsections (e.g., Participants, Experimental Design, and Statistical Analysis ), and make sure you follow specific journal formatting styles when doing so. 

If the journal you submit to follows APA style , for example, you are allowed to use up to five levels of headings, depending on the length of your paper, the complexity of your work, and your personal preference. To clearly indicate how each subsection fits into the rest of the text, every header level has a different format – but note that headers are usually not numbered because the different formatting already reflects the text hierarchy.

APA style headings example structure

Level 1 Centered, Bold, Title Case

Text begins as a new paragraph.

Level 2 Left-aligned, Bold, Title Case

Level 3 Left-aligned, Bold Italic, Title Case

Level 4     Indented, Bold, Title Case, Period . Text begins on the same                    

                                 line and continues as a regular paragraph.

Level 5     Indented, Bold Italic, Title Case, Period. Text begins on the                           

                                 same line and continues as a regular paragraph.

If you only need one section header (e.g. Methods ) and one level of subsection headers (e.g., Participants, Experimental Design, and Statistical Analysis ), use Level 1 and Level 2 headers. If you need three levels of headings, use Levels 1, 2, and 3 (and so on). Do not skip levels or combine them in a different way. 

If you write a paper in Chicago style or MLA style , then you don’t need to follow such exact rules for headings and subheadings. Your structure just has to be consistent with the general formatting guidelines of both styles (12-pts Times New Roman font, double-spaced text, 0.5-inch indentation for every new paragraph) and consistent throughout your paper. Make sure the different formatting levels indicate a hierarchy (e.g., boldface for level 1 and italics for level 2, or a larger font size for level 1 and smaller font size for level 2). The main specifics regarding Chicago and MLA headings and subheadings are that they should be written in title case (major words capitalized, most minor words lowercase) and not end in a period. Both styles allow you, however, to number your sections and subsections, for example with an Arabic number and a period, followed by a space and then the section name. 

MLA paper headings example structure

1. Introduction

2. Material and Methods

2.1 Subject Recruitment

2.2 Experimental Procedure

2.3 Statistical Analysis

3.1 Experiment 1

3.2 Experiment 2

4. Discussion

5. Conclusion

What research paper headings do you need?

Your paper obviously needs to contain the main sections ( Introduction, Methods, Results, Discussion, and maybe Conclusion ) and you need to make sure that you name them according to the target journal style (have a look at the author guidelines if you are unsure what the journal style is). The differences between journals are subtle, but some want you to combine the results and discussion sections, for example, while others don’t want you to have a separate conclusion section. You also need to check whether the target journal has specific rules on subsections (or no subsections) within these main sections. The introduction section should usually not be subdivided (but some journals do not mind), while the method section, for example, always needs to have clear subsections.

How to Name Your Sections and Subsections

The method section subheadings should be short and descriptive, but how you subdivide this section depends on the structure you choose to present your work – which can be chronological (e.g., Experiment 1, Experiment 2 ) or follow your main topics (e.g., Visual Experiment, Behavioral Experiment, Questionnaire ). Have a look at this article on how to write the methods for a research paper if you need input on what the best structure for your work is. The method subheadings should only be keywords that tell the reader what information is following, not summaries or conclusions. That means that “ Subject Recruitment ” is a good methods section subheading, but “ Subjects Were Screened Using Questionnaires ” is not.  

The subheadings for the result section should then follow the general structure of your method section, but here you can choose what information you want to put in every subheading. Some authors keep it simple and just subdivide their result section into experiments or measures like the method section, but others use the headings to summarize their findings so that the reader is prepared for the details that follow. You could, for example, simply name your subsections “ Anxiety Levels ” and “ Social Behavior ,” if those are the measures you studied and explained in the method section. 

Or, you could provide the reader with a glimpse into the results of the analyses you are going to describe, and instead name these subsections “ Anxiety-Like Behaviors in Mutant Mice ” and “ Normal Social Behaviors in Mutant Mice .” While keeping headings short and simple is always a good idea, such mini-summaries can make your result section much clearer and easier to follow. Just make sure that the target journal you want to submit to does not have a rule against that. 

Common Heading and Subheading Mistakes 

Subheadings are not sentences.

If your heading reads like a full sentence, then you can most probably omit the verb or generally rephrase to shorten it. That also means a heading should not contain punctuation except maybe colons or question marks – definitely don’t put a period at the end, except when you have reached heading level 4 in the APA formatting style (see above) and the rules say so.  

Be consistent

Always check your numbering, for example for spaces and periods before and after numbers (e.g., 3.2. vs 3.2 ), because readability depends on such features. But also make sure that your headings are consistent in structure and content: Switching between short keyword headings (e.g., “ Experiment 2 ”) and summary headings (e.g., “ Mice Do not Recognize People ”) is confusing and never a good idea. Ideally, subheadings within a section all have a similar structure. If your first subsection is called “ Mice Do not Recognize People ,” then “ People Do not Recognize Mice” is a better subheader for the next subsection than “Do People Recognize Mice? ”, because consistency is more important in a research paper than creativity. 

Don’t overdo it

Not every paragraph or every argument needs a subheading. Only use subheadings within a bigger section if you have more than one point to make per heading level, and if subdividing the section really makes the structure clearer overall.

• Comprehensive Guide to Headings and Subheadings in APA 7.0

Section 1: Introduction to Headings and Subheadings in APA 7.0-

In academic writing, the use of headings and subheadings is crucial for organizing and structuring a paper. APA (American Psychological Association) style, specifically in its 7th edition, provides clear guidelines on how to effectively use headings and subheadings to enhance readability and comprehensibility of research papers, essays, and other scholarly works. This section will provide a comprehensive introduction to the importance, purpose, and benefits of using headings and subheadings in APA 7.0 format.

Purpose of Headings and Subheadings

Headings and subheadings serve as visual cues to help readers navigate through the content of a paper. They create a hierarchical structure, indicating the relationships between different sections and subsections, and aid in organizing ideas and presenting information in a logical manner. By using headings and subheadings, writers can effectively divide their work into manageable and coherent sections, making it easier for readers to comprehend and follow the main arguments and supporting details.

Importance of Headings and Subheadings

Clear and well-structured headings and subheadings are essential in academic writing for several reasons. First and foremost, they enhance the overall readability of the paper by breaking down the text into smaller, digestible chunks. This organization allows readers to quickly identify and locate specific information, especially when they are scanning or skimming through the document.

Secondly, headings and subheadings contribute to the coherence and flow of the paper. By providing a clear roadmap, they guide the reader through the main ideas, supporting evidence, and key points presented in each section. This not only improves the overall structure of the paper but also helps maintain the logical progression of thoughts and arguments.

Additionally, headings and subheadings assist both readers and writers in comprehending complex topics. They enable writers to organize their thoughts, ensuring that each section focuses on a specific aspect or theme. This organization facilitates a deeper understanding of the subject matter for both the writer during the drafting process and the reader during the consumption of the paper.

Formatting Guidelines for Headings and Subheadings

APA 7.0 provides specific rules and formatting guidelines for using headings and subheadings. These guidelines include the use of different levels of headings, capitalization rules, and placement within the paper. Understanding and adhering to these guidelines is crucial for maintaining consistency and conformity with APA style.

The APA 7.0 formatting guidelines for headings and subheadings are based on a five-level hierarchy, with each level indicating the level of importance and hierarchy of information. Level 1 headings are the highest level, followed by Level 2, Level 3, and so on. Each level has a specific formatting style, such as font size, boldness, and indentation, to differentiate it from the other levels. Furthermore, APA 7.0 also provides guidance on the appropriate use of sentence case, title case, and capitalization in headings and subheadings. For instance, Level 1 headings are typically written in sentence case and are centered and bolded. Level 2 headings are aligned to the left margin, bolded, and written in title case. To maintain clarity and consistency, APA 7.0 also provides recommendations on the number of headings to use within a paper. It suggests that at least two headings should be used in any given section, as a single heading alone may not adequately represent the content covered.

Section 2: The Purpose and Importance of Headings and Subheadings in APA 7.0

Facilitating information retrieval.

One of the primary purposes of headings and subheadings in APA 7.0 is to facilitate information retrieval for readers. When faced with a lengthy document, readers often engage in scanning or skimming techniques to locate specific information or sections of interest. Well-structured headings and subheadings act as signposts, allowing readers to quickly identify the content they are seeking without having to read the entire text. By providing a clear and organized hierarchy, headings guide readers to the main sections of a paper, while subheadings further break down the content into more specific subsections. This hierarchical structure enables readers to navigate the document with ease, locating relevant information efficiently. Thus, headings and subheadings in APA 7.0 contribute significantly to the overall accessibility and user-friendliness of academic papers.

Enhancing Readability and Comprehensibility

Headings and subheadings play a vital role in enhancing the readability and comprehensibility of academic writing. They help break up large blocks of text into smaller, digestible sections, preventing the overwhelming feeling that dense paragraphs can create. By visually separating different sections and subsections, headings and subheadings allow readers to mentally prepare for the content they are about to encounter. Additionally, headings and subheadings improve the flow and coherence of a paper. They provide a roadmap for readers, helping them understand the organization and structure of the author's arguments and supporting evidence. Well-crafted headings and subheadings enable readers to follow the logical progression of ideas and maintain a clear understanding of the paper's main points. Finally, headings and subheadings aid in the comprehension of complex topics. By breaking down the content into smaller, focused sections, readers can grasp the material more easily. Headings act as cognitive cues, preparing readers for the information presented in each section. This approach not only facilitates understanding but also allows readers to engage with the content at a deeper level, promoting knowledge retention.

Organizing and Structuring Ideas

Headings and subheadings in APA 7.0 serve as valuable tools for organizing and structuring ideas within a paper. They help writers divide their work into meaningful sections, each addressing a specific aspect or theme related to the overall topic. This organization ensures that information is presented in a coherent and logical manner, making it easier for both the writer and the reader to navigate the paper.

By using headings and subheadings, writers can create a clear outline for their work, ensuring that each section has a distinct focus. This outline acts as a framework, guiding the writer in presenting their arguments and supporting evidence in a systematic and organized way. Writers can use headings to delineate major sections or main ideas, while subheadings allow for further subcategorization and exploration of subtopics.

Furthermore, headings and subheadings assist writers in structuring their thoughts during the writing process. By providing a visual representation of the paper's organization, headings help writers maintain a coherent flow of ideas and prevent the inclusion of irrelevant or tangential information. This structured approach not only improves the overall quality of the paper but also enhances the writer's ability to communicate their ideas effectively.

Conveying the Hierarchical Relationship of Information

Another important purpose of headings and subheadings in APA 7.0 is to convey the hierarchical relationship of information. By assigning different levels to headings, the writer can indicate the relative importance and order of ideas within the paper. Higher-level headings represent broader themes or major sections, while lower-level headings address more specific subtopics or subsections. This hierarchical structure helps readers understand the organization and logical flow of the paper at a glance. It allows them to grasp the overall structure and the relationships between different sections without having to read the entire document. Additionally, the use of indentation and formatting styles for each level of heading further reinforces the hierarchical relationship and aids in visual differentiation.

Section 3: Formatting Guidelines for Headings and Subheadings in APA 7.0

Proper formatting of headings and subheadings is crucial in APA 7.0 style to ensure consistency, clarity, and readability in academic writing. This section will delve into the specific formatting guidelines provided by APA 7.0 for headings and subheadings, including the use of different levels, capitalization rules, and placement within the paper.

Levels of Headings

APA 7.0 introduces a five-level hierarchy for headings, each denoting a different level of importance and significance within the paper. These levels provide a structured framework for organizing the content and help readers understand the organization and flow of ideas. Here are the five headings in APA 7.0:

Level 1: Centered, Bold and Title Case

            Text begins here.

Level 2: Left-Aligned, Bold and Title Case

Level 3: Left-Aligned, Bold, Italics, and Title Case

Level 4: Left-Aligned, Bold, Title Case, and Period. Text begins here.

Level 5: Left-Aligned, Bold, Title Case, Italics, and Period . Text begins here.

Section 4: Organizing and Structuring Your Paper

Using headings and subheadings in apa 7.0.

Organizing and structuring your paper effectively is crucial for presenting your ideas in a logical and coherent manner. Headings and subheadings in APA 7.0 play a vital role in achieving this goal by providing a clear framework for organizing your content. This section will delve into strategies and best practices for utilizing headings and subheadings to organize and structure your paper in accordance with APA 7.0 guidelines.

Preparing an Outline

Before you begin writing your paper, it is helpful to create an outline that outlines the main sections and subsections you intend to cover. An outline acts as a roadmap, allowing you to visualize the overall structure and flow of your paper. It serves as a foundation for developing meaningful headings and subheadings that accurately represent the content and facilitate logical organization. Start by identifying the major sections that your paper will include, such as introduction, literature review, methods, results, discussion, and conclusion. These major sections will serve as Level 1 headings in APA 7.0. Next, break down each major section into subsections that address specific subtopics or aspects related to the main theme. These subsections will be represented by Level 2 headings. Depending on the complexity and depth of your paper, you may further divide the subsections into sub-subsections using Level 3, Level 4, and Level 5 headings. Creating a comprehensive outline not only helps you organize your thoughts but also ensures that you cover all the necessary components of your paper. It allows you to see the relationships between different sections and subsections, enabling you to present your arguments and evidence in a logical and coherent sequence.

Maintaining Consistency and Parallelism

Consistency is key when it comes to organizing and structuring your paper using headings and subheadings. It is important to establish a consistent framework that is followed throughout the entire document. Consistency ensures that readers can easily understand the hierarchy and relationships between different sections and subsections. When creating headings and subheadings, aim for parallelism in terms of grammatical structure and formatting. Parallelism means that headings at the same level should have a similar grammatical structure and formatting style. For instance, if you choose to use noun phrases for Level 2 headings, maintain this pattern consistently across all Level 2 headings in your paper. This helps readers navigate through the content smoothly and maintain a sense of coherence. Furthermore, parallelism extends to the use of punctuation and capitalization within headings and subheadings. Maintain consistent capitalization rules, such as sentence case for Level 1 headings and title case for Level 2 headings. This uniformity enhances the visual hierarchy and clarity of your paper.

Balancing Depth and Granularity

Effective organization and structuring involve finding the right balance between depth and granularity in your headings and subheadings. Level 1 headings represent major sections and should encapsulate broad themes or concepts, providing an overview of what will be discussed within each section. Level 2 headings, as subsections, delve into more specific topics or aspects related to the main theme of the major section.

Reviewing and Revising the Organization

Organizing and structuring your paper using headings and subheadings is not a one-time task. It is an iterative process that requires regular review and revision to ensure optimal clarity and coherence. Once you have completed the initial draft of your paper, review the organization of your headings and subheadings. Ask yourself if the structure effectively reflects the flow of your ideas and supports your main argument. Consider whether the headings accurately represent the content of each section and subsection. During the review process, pay attention to transitions between sections and subsections. Ensure that the headings and subheadings create a smooth transition from one topic to another, guiding readers through the logical progression of your paper. If you notice any gaps or inconsistencies, revise and refine the organization accordingly. Additionally, seek feedback from peers, mentors, or instructors. Their fresh perspective can provide valuable insights into the clarity and effectiveness of your headings and subheadings. Incorporate their feedback and make necessary adjustments to improve the overall organization and structure of your paper.

Section 5: Common Mistakes to Avoid in Using Headings and Subheadings in APA 7.0

While using headings and subheadings in APA 7.0 can greatly improve the organization and readability of your paper, it's important to be aware of common mistakes that can compromise the effectiveness of your headings. By understanding and avoiding these mistakes, you can ensure that your headings enhance the clarity and coherence of your academic writing. This section will explore some common mistakes to avoid when using headings and subheadings in APA 7.0.

Inconsistent Formatting

One of the most common mistakes is inconsistent formatting of headings and subheadings. In APA 7.0, it is crucial to maintain consistency in capitalization, alignment, and formatting styles across headings at the same level. Inconsistencies can confuse readers and disrupt the visual hierarchy of your paper. Ensure that all Level 1 headings have the same formatting, all Level 2 headings have the same formatting, and so on. Consistency in formatting contributes to the overall professionalism and readability of your work.

Poor Alignment and Spacing

Another mistake to avoid is incorrect alignment and spacing of headings and subheadings. In APA 7.0, Level 1 headings are centered and typically start on a new page or a new line with an extra line space before and after the heading. Level 2 headings and lower-level headings, however, are left-aligned and generally require an extra line space before the heading but not after. Failure to align and space headings correctly can create confusion and disrupt the logical flow of your paper. Review APA 7.0 guidelines carefully to ensure proper alignment and spacing of your headings.

Lack of Parallelism

Parallelism, or consistent grammatical structure, is crucial when using headings and subheadings. Headings at the same level should follow a similar structure to maintain coherence and readability. For example, if you use noun phrases for Level 2 headings, ensure that all Level 2 headings follow this pattern. Lack of parallelism can make your headings appear disjointed and may confuse readers. Consistently apply parallel structure within each level of headings to create a smooth and organized flow of information.

Overcomplicating the Heading Structure

While it is important to provide a clear and hierarchical structure to your paper, overcomplicating the heading structure can lead to confusion and excessive fragmentation. Strive to find a balance between providing enough detail to cover your content effectively and avoiding an excessive number of headings and subheadings. Each heading should represent a meaningful subdivision and contribute to the overall organization and coherence of your paper. Aim for a clear and concise heading structure that guides readers without overwhelming them with excessive levels or overly specific subdivisions.

Lack of Descriptiveness

Headings and subheadings should be descriptive and informative to accurately represent the content covered within each section. Avoid using generic or ambiguous headings that do not provide a clear indication of what readers can expect to find. Vague headings can leave readers uncertain about the content or make it challenging to locate specific information within your paper. Ensure that your headings succinctly capture the main ideas or themes of each section, guiding readers through your content effectively.

Ignoring the Reader's Perspective

When creating headings and subheadings, it's important to consider the perspective of your readers. Put yourself in their shoes and think about how your headings will facilitate their understanding and navigation through your paper. Consider whether your headings effectively communicate the main points, guide readers through the logical flow of your arguments, and enable them to locate specific information easily. Ignoring the reader's perspective can result in headings that are unclear, unhelpful, or inconsistent, hindering the overall readability and comprehension of your work.

Neglecting to Revise and Edit Headings

Headings should not be an afterthought or treated as static elements in your paper. Neglecting to revise and edit your headings can lead to inaccuracies, lack of clarity, or poor alignment with the final content of your paper. As you progress through the writing process, continuously review and refine your headings to ensure they accurately represent the content and flow of your arguments. Make necessary adjustments, reword headings for better clarity, and ensure that they align with the finalized structure and organization of your paper.

Table of Contents

APA headings and subheadings refers to the rules for formatting sections of documents in the 7th Edition of the American Psychological Association’s Publication Manual .

A research paper written in APA style should be organized into sections and subsections using the five levels of APA headings. 

Related Concepts:

Notice how sections contain at least two smaller subsections in the example below:

Design  

Participants. , demographics..

Characteristics.

Limitations

Starting with the first level of heading, the subsections of the paper should progressively use the next level(s) of heading without skipping any levels. Major sections of the paper’s main body, including the Method, Results, and Discussion sections, should always be formatted with the first level of heading. However, keep in mind that the Introduction section, which is preceded by the full title of the paper, should be presented in plain type. Any subsections that fall under the major sections are formatted with the next level of heading.

Note that all paragraphs of the main body, including those that fall under subsections of a larger section, still maintain the pattern of indentation, use Times New Roman font, 12 pt., and are double-spaced. There are no extra lines or spaces between paragraphs and headings.

How are the five levels of APA-style headings formatted?

Format each of the five levels of APA-style headings as demonstrated in the example below. Note that while the example features headings titled “First Level,” “Second Level,” and so on, each heading in your paper should be named according to the section it describes. 

First level

The first level of heading is bolded and centered, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Second level

The second level of heading is bolded and situated flush left, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Third level

The third level of heading is bolded, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fourth level

The fourth level of heading is bolded, italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fifth level

The fifth level of heading is italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Method  (1st level)

Design (2nd level)

        Participants (3rd level)

        Demographics. (4th level)

              Age Group. (5th level)

Limitations  (2nd level)

• For student papers, include only the page number in the top right margin of every page of the paper
• For professional papers, place the page number in the top right margin and the running head in the top left margin of every page of the paper. Running heads should be a shortened version of the paper title.

APA headings and subheadings provide a clear structure to your document and make it easy to navigate through. This is especially beneficial when it comes to longer documents. 

The APA format makes use of headings and subheadings to indicate a hierarchy. But what is an APA paper heading and how do you customize it? We will answer all these questions with the help of concrete examples and templates.

Let’s start off with understanding the basics of how to customize these APA format headings and subheadings. 

APA heading format

There are five APA heading levels that can be used as per the latest APA guidelines. You can decide which level of heading to use, depending on the length and complexity of your document.

• The level 1 heading is the main APA heading for your paper, which is used to indicate all the major sections (excluding the introduction). 
• The level 2 heading is included under the level 1 heading and is used to indicate its different aspects.
• The level 3 heading is used to indicate the subpoints to be included under the level 2 heading and so on.

Here are the formatting guidelines for the APA heading formats for the 7th edition:

• Avoid creating too many subheadings. This makes your document shabby and difficult to understand. 
• Do NOT number the APA-style headings and subheadings. The APA paper format does not make use of Roman and Arabic letters and numerals to number the headings.
• Include a double space between the content and the heading for the first 3 levels.
• Use the title case for all your headings.
• Avoid creating a single APA subheading under the parent heading. 

Let’s take a look at how to format each of these APA heading levels in more detail.

APA heading levels

As stated above, the APA Style guide consists of 5 levels of headings. Each level heading should be bolded and in some cases italicized . Here are the guidelines for the five APA format headings:

APA level 1 heading

The level 1 heading for an APA paper is the main heading in an APA-style paper. It is used for all the significant sections of the paper such as “Methods”, “Results”, and “Discussion”. 

Do NOT include the Introduction in the level 1 heading. The heading of your paper present in the APA title page serves as a de facto heading for your introduction. 

Here are the formatting guidelines for an APA level 1 heading:

• Centrally align and bold the heading.
• Leave a double space between the heading and the text under it. 
• Begin writing the text on a new line, leaving an indent 0.5 inches from the left margin. 

Here is the APA heading format example:

APA Level 1 Heading

The text is indented and begins on a new line.

A section label is used to indicate specific parts of your paper including. It is similar to a level 1 heading but is formatted slightly differently. It is bolded and centrally aligned but is placed in a separate line at the top of a new page. 

APA level 2 heading

A level 2 heading is a subsection that is included under the level 1 heading. For instance, subheadings such as “Test Sample” are included under the main heading “Method”. Make sure that there are two or more subheadings present under each main heading. 

The level 2 APA subheading format is as follows:

• Left align and bold the heading.
• Leave a double space between your heading and the text pertaining to it.
• Leave an indent and begin writing the text on a new line.

Here is a level 2 APA heading example:

APA Level 2 Heading

APA level 3 heading

Level 3 APA subheadings are used to further categorize characteristics included under the level 2 subheading. For instance, the level 2 subheading “Test Sample” may further be divided into sample groups such as “Preteens”, “Adolescents”, and “Adults” . 

Here are the formatting guidelines for an APA level 3 heading:

• Left align, bold, and italicize the heading.
• Leave space between the heading and the text included below it.
• Leave a 0.5-inch indent and begin writing the text on a new line.

Here is a level 3 APA heading example:

APA Level 3 Heading

APA level 4 heading

The level 4 APA subheadings are rarely used when it comes to school papers. They’re more often used in more complex and detailed papers such as postgraduate or professional research papers. It is used to further categorize information included in the level 3 heading. For instance, the sample group of “Preteens” can further be divided into categories such as “Children (6–8 years)” and “Children (9–12 years)”.  

Following are the formatting guidelines for an APA level 4 heading:

• Left align, indent, and bold the heading.
• End the heading with a period.
• Begin writing the text after the period in the same line.

Here is a level 4 APA heading example:

APA Level 4 Heading. The text begins in the same line.

APA level 5 heading.

The level 5 heading is the final heading included under the APA formatting guidelines. It is used to further categorize information included under the level 4 heading. For instance, the category “Children (6–8 years)” can be further divided into “Boys” and “Girls”.

Following are the formatting guidelines for an APA level 5 heading:

• Left align, indent, bold, and italicize the heading.
• End your heading with a period.

Here is a level 5 APA heading example:

APA Level 5 Heading. The text begins in the same line.

When you put all of the headings together, it should look something like this:

APA Level 5 Heading . The text begins in the same line.

APA heading format for Microsoft Word and Google Docs

Things get much easier when it comes to formatting APA headings in MS Word and Google Docs. Instead of individually inserting each heading, you can simply make use of the “styles” feature. This allows you to select a heading of your choice with a single click.

Make sure to edit your heading as per the APA formatting guidelines, since these default settings are not available in MS Word or Google Docs.  

APA heading example

To understand how the APA levels are structured, let’s take a look at an APA format for headings. The following research paper outline highlights the methods used to collect the effect of coffee on preteens and young adults. 

Here’s how the headings and text should be structured in the following example.

If you think formatting is not your strong suit and you want to make things easier, consider working with professional editing services . These professionals not only correct structural errors and content flow but also rectify all proofreading errors.

APA Headings and Subheadings

• Discussion Section
• Websites and Online Sources
• Journals and Periodicals

• Other Non-Print Sources
• In-text Citations
• Footnotes and Endnotes
• Using MyBib Responsibly
• Miscellaneous Questions

There are five levels of headings available to use in an APA formatted paper. These headings indicate the hierchy of the information within the paper.

For example, if your paper contains the standard main sections Method , Results , and Discussion , these should all use the first-level heading.

• Method (level one)
• Results (level one)
• Discussion (level one)

If you want to include Participants and Instruments within the Method section, you would make these a level two heading.

• Participants (level two)
• Instruments (level two)

A subsection of Participants , like Age or Race , would be level three headings. This pattern continues down to level five headings.

• Age (level three)
• Race (level three)

Styling the Different Headings

Each level has specific formatting requirements to make it visibly obvious which level it is. As with all other text in an APA formatted paper, the font size should be 12pt. The differences between each level are as follows:

Level One Heading

Level one headings are centered and bolded, with all major words capitalized (articles and conjunctions are not captalized).

Level Two Heading

Level two headings are similar to level one headings, except are aligned on the left.

Level Three Heading. Level three headings are similar to levels one and two, except they're indented by 5 spaces, followed by a period, and the text following the heading does not start on a new line.

Level Four Heading. The level four heading is identical to level three, except it is also italicized.

Level Five Heading. Finally, the level five heading is identical to level four, except it is no longer bold.

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

APA Headings and Subheadings

The use of headings and subheadings give the readers a general idea of what to expect from the paper and leads the flow of discussion. These elements divide and define each section of the paper. APA recommends five-level heading structure based on the level of subordination.

• 2 Guideline
• 4  A Couple of Writing Tips

Levels indicate the hierarchy of importance and scope of each heading and subheading. The extent of using the different levels depends on the length and complexity of the paper. Usually, short papers or articles use two to three levels, but longer papers necessitate up to five levels. Level 1 encompasses a broader topic and levels 2 to 5 covers narrow to more detailed topics.

Level 1 Section heading

Level 2 Subsection heading

Level 3 Subsection of a subsection heading

Level 4 Subsection under a subsection of a subsection heading

Level 5 Subsection under the three subsections heading

• No heading is needed for the first part of a paper as it is already assumed as the introduction.
• Headings and subheadings are not accompanied by letters or numbers.
• Use as many levels as required in your paper to present the most organized structure.
• The same level of heading or subheading should be of equal importance regardless of the number of subsections under it.
• Use at least two subheadings for each section and subsection, or use none.
• Start with level 1 through 5.
• Paragraph begins below levels 1 and 2, whereas for levels 3-5, the paragraph begins in line with the headings.
• Capitalize each word for levels 1 and 2.
• For levels 3-5, the headings are indented and end with a period.
• Only the first word is capitalized for levels 3-5.

To give you a clearer picture, here is the recommended format and example for the heading levels.

Methods (Level 1)

Research Design (Level 2)

Paragraph begins here…

Study Site and Participant (Level 2)

Data Collection (Level 2)

Instruments. (Level 3) Paragraph begins here…

Procedures. (Level 3) Paragraph begins here…

Socio-demographic and medical history data gathering. (Level 4) Paragraph begins here…

Anthropometric and body composition assessment. (Level 4) Paragraph begins here…

Dietary assessment. (Level 4) Paragraph begins here…

Three-day food record. (Level 5) Paragraph begins here…

Semi-qualitative FFQ. (Level 5) Paragraph begins here…

 A Couple of Writing Tips

Writing is meant to communicate ideas and get our points across as clearly and as effective as possible. But no matter how informative your writing is, it wouldn’t be as valuable if it is incoherent. You have to write in such a way that every part of your paper will have a logical sequence and sound structure to make it comprehensive and easy to understand. There are certain ways in writing a clear and concise paper, and here are simple tips which are especially useful for scientific studies:

First, state your points clearly and precisely .

Second , integrate parts with relevant or similar information to avoid repetition .

Third, use an active voice .

And fourth, organize the structure of your paper.

As a writer, I think the most important among the aforementioned tips is the organization of structure. Once you have a complete picture of what you will include in your paper, everything else will follow.

Formatting APA Headings and Subheadings

• Writing Research Papers
• English Grammar
• M.Ed., Education Administration, University of Georgia
• B.A., History, Armstrong State University

In American Psychological Association style, APA headings and subheadings are used to give readers a general idea of the content and what to expect from a paper , and it leads the flow of discussion by dividing up a paper and defining each section of the content.

APA style is different than Modern Language Association style , which is used in most humanities courses, and Chicago style , which is used in most history courses. There are some differences between APA, MLA, and Chicago style headings in papers, particularly on the title page as well as at the top of subsequent pages.

Fast Facts: APA Headers

• APA style is generally used for social science research papers.
• There are five heading levels in APA. The 6th edition of the APA manual revises and simplifies previous heading guidelines

APA uses something called a "running head," while the other two styles do not. MLA uses a left-indented topper for the paper author's name, the professor's name, the course name, and date, while MLA and Chicago style do not. So it's important to use the correct style for APA headings when formatting a paper in APA style. APA style uses five levels of headings.

APA Level Headings

​APA style recommends using a five-level heading structure based on the level of subordination. Purdue OWL notes the APA headings levels as follows:

The sections named above are considered major elements of your paper, so these sections should be treated as the highest level of headings. Major levels (highest level) titles in your APA title are centered on your paper. They should be formatted in boldface and the important words of the heading should be capitalized .

In addition to the above rules, headings and subheadings also should not be accompanied by letters or numbers. You should use as many levels as required in your paper to present the most organized structure. Not all five levels should be used, but the same level of heading or subheading should be of equal importance regardless of the number of subsections under it.

For level one and two headings, paragraphs should begin under the heading on a new line, and these levels should capitalize each word in the heading. However, levels three through five should have the paragraph begin in line with the headings, and only the first word is capitalized. In addition, in levels 3-5, the headings are indented and end with a period.

Example APA-Formatted Paper

The following shows, in part, what an APA-formatted paper would look like. Where needed, explanations have been added to indicate the placement or formatting of the headers:

Research shows that developmentally disabled individuals need skills training in order to be able to function independently as adults (Flannery, Yovanoff, Benz & Kato (2008), Sitlington, Frank & Carson (1993), Smith (1992). There is a need for further research detailing what kinds of services are important to success, such as reinforcement of domestic, vocational and social skills, as well as financial planning . This paper proposes to answer the question: What is the effect of services provided by Regional Centers on the independent living skills of developmentally disabled adults?

The Independent Variable would be services provided by Regional Centers. The dependent variable would be independent living skills of developmentally disabled adults. I will test my hypothesis – that such services could lead to greater independence in developmentally disabled adults – by examining living skills of a group of developmentally disabled adults with services provided by Regional Centers to a group of developmentally disabled adults who do not receive Regional Center services. I will establish this “control” group by examining a similar group of individuals who have sought – but refused – Regional Center services.

Benefits of the research

An abundance of literature reveals a great need for better transitional services for developmentally delayed individuals leaving high school and entering adulthood (Nuehring & Sitlington, 2003, Sitlington, et. al., 1993, Beresford, 2004). Many of the studies focus on transitional services needed to aid developmentally disabled adults move successfully from high school to the adult working world (Nuehring & Sitlington, 2003, Sitlington, et. al., 1993, Flannery, et. al., 2008). Yet, some of those same researchers note that most developmentally disabled adults do not work after high school (Sitlington, et. al.,

RESEARCH PROPOSAL

1993). More recently (and even in older studies), researchers have begun to note that developmentally delayed adults need services to help them succeed in adulthood in a variety of areas needed for successful independent living, such as living arrangements, financial and budgeting skills, relationships, sex, aging parents, grocery shopping and a host of other issues (Beresford, 2004, Dunlap, 1976, Smith, 1992, Parker, 2000). Few agencies exist nationally to provide such services to developmentally delayed individuals from birth through adulthood. However, in California, a group of 21 Regional Centers provides services to developmentally delayed adults ranging from life-planning, funding of services and equipment, advocacy, family support, counseling, vocational training, etc. (What are regional Centers? n.d.). The purpose of this study, then, is to determine the effects of Regional Center services on the independent living skills of disabled adults.

Literature Analysis (centered)

Smith (1992) notes that many developmentally disabled adults fall “through the cracks” once they reach adulthood. Smith used a survey method to examine the success or lack thereof of 353 developmentally disabled adults. Smith noted that 42.5% were employed full time, 30.1% were employed part time and 24.6% were unemployed. In discussing results, Smith noted that what was needed to improve the employment situation of these individuals was to ensure that they learn how to access Vocational Rehabilitation services and that those providing services –vocational rehabilitation counselors, teachers, and other professionals -- be better trained in reaching out to such individuals. In other

words, if developmentally delayed adults simply had better access to vocational rehabilitation services (the independent variable), they would somehow become more successful in terms of full-time employment. Smith provides no empirical evidence to demonstrate how or why this would occur.

Synthesis of Literature Relevant to the Research Proposition

Sitlington, et. al. (1993) imply that if developmentally delayed individuals are not successful in adulthood, it is, essentially, their fault. Sitlington, et. al. give no indication that providing vocational services alone may not be enough. And, there is nothing in Sitlington, etc....

Title Page, Abstract, and Introduction

The title page is considered the first page of an APA paper. The second page will be the page containing an abstract. Because the abstract is a main section, the heading should be set in boldface and centered on your paper. Remember that the first line of an abstract is not indented. Because the abstract is a summary and should be limited to a single paragraph, it should not contain any subsections.

Every paper begins with an introduction, but according to APA style, an introduction should never carry a heading that labels it as such. APA style assumes that the content that comes at the beginning is an introduction and therefore doesn't require a heading.

As always, you should check with your instructor to determine how many main (level-one) sections will be required, as well as how many pages and sources your paper should contain.

Setting the Normal Style

Set the "normal" style of font.

Before we can set up headings, we'll need to define the format of the text that  isn't  a heading. The "styles" in word set some default formatting for text. Setting up the "Normal" style will create a default font setting to keep the text uniform throughout the document. The Styles pane is located under the HOME tab.

Right click on the "Normal" style to open the Modify option.

This will open a Modify Style Dialog Box. Start by changing the Paragraph formatting. This is located by selecting the Format drop down in the bottom left of the Dialog Box.

There are two things that should be set under the Paragraph settings. Under the INDENTS AND SPACING tab, check to turn on "Don't add space between paragraphs of the same style." Under the LINE AND PAGE BREAKS tab, check to turn on the "Widow/Orphan Control."

Once both of those have been set and you click "okay," you'll be returned to the Modify Style Dialog Box. Now we can set the font formatting. Select the font you wish to use throughout the document, change the font size to 12 point, ensure the line spacing is double spaced, and select the option to remove space between paragraphs (this is indicated by two lines pointing towards each other).

Adding Headings & Subheadings

Inserting headings and subheadings.

Using the same technique we can create a standard for the various types of headings and subheadings used across the thesis. The Thesis & Dissertation Manual generally follows APA style for heading levels. In order to keep headings consistently correct and link the Table of Contents, the Styles function in Word is used. This is going to show you some examples of the formatting required for the headings and how to use the various heading levels. We'll also see how to use styles and update your Table of Contents. 

Modifying Heading Levels to Match Required Formatting

Level 1 headings.

Chapters will be linked to Heading Level 1. If you choose not to have chapters, you will use level 1 for your major headings (typically: Introduction, Literature Review, Methods, etc.). They should be typed in title case, center aligned, and bold. The number of the chapter can be in Arabic or Roman numerals or spelled out so long as it is consistently done throughout the document. The heading should be on one line, so if you are using chapters, it should look something like this:

Chapter 1: Introduction

Once you have formatted a chapter heading, select the text of the chapter heading then right click on Heading 1 in the Styles pane and select "Update Heading 1 to Match Selection." 

Adding More Level 1 Headings

Once you have formatted the first heading and updated the style, you simply need to type the new level 1 heading in title case and then, with your cursor in line with the heading, click on the heading 1 button in the styles pane to format it and link it for your table of contents. Make sure to use this feature every time to ensure all headings are properly linked to your table of contents.

Level 2 Headings

Subsections of your major headings should be the next level down. Level 2 headings will be left aligned, bold, and title case. They should look like this:

Level 2 Heading

Once you have formatted a level 2 heading, select the text of the heading then right click on Heading 2 in the Styles pane and select "Update Heading 2 to Match Selection." 

Adding More Level 2 Headings

Once you have formatted the first heading and updated the style, you simply need to type the new level 2 heading in title case and then, with your cursor in line with the heading, click on the heading 2 button in the styles pane to format it and link it for your table of contents. Make sure to use this feature every time to ensure all headings are properly linked to your table of contents.

Level 3 Headings

If you wish to further subsection your paper, you will use level 3 headings. Level 3 headings will be bold italic, left aligned, and title case. They should look like this:

Level Three Heading

Once you have formatted a level 3 heading, select the text of the heading then right click on Heading 3 in the Styles pane and select "Update Heading 3 to Match Selection." 

Adding More Level 3 Headings

Once you have formatted the first heading and updated the style, you simply need to type the new level 3 heading in title case and then, with your cursor in line with the heading, click on the heading 3 button in the styles pane to format it and link it for your table of contents. Make sure to use this feature every time to ensure all headings are properly linked to your table of contents.

Level 4 & 5 Headings (and beyond)

It is common to find the first 3 heading levels in papers that are as long as a thesis or dissertation. Occasionally, you may find the need to go beyond those levels. It is important to note that for the thesis and dissertation, only the first 3 headings should be included in the table of contents. It is also recommended that you only use the styles function for the first 3 headings because they stand alone on their own line of text. The next heading levels will begin on the same line as the paragraph that starts that section which means that the style function will not work properly. If you were to link the heading, the entire paragraph will appear in your table of contents.

This means that you will need to, carefully, ensure you are formatting the headings manually. Each level should be consistently formatted the same way. APA has standards for levels 4 & 5 which are described here. For heading levels beyond level 5, you should pick a consistent formatting that clearly indicates they are a subsection of the level 5 heading. It is also recommended that you carefully evaluate if this level of heading is truly necessary for your writing.

Level 4 Heading

Level 4 headings will begin on the same line of the paragraph that makes up the section. It will be indented 0.5", much like a normal paragraph indent. The heading will be in title case and bold font with a period at the end of the heading:

            Level Four Heading Here.  Start the first sentence of the paragraph that follows the heading on the same line and continue typing. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc at pellentesque massa. Sed nec urna nec est efficitur iaculis. Etiam efficitur velit id dignissim eleifend. Duis euismod, nisi sed cursus sodales, sem nisi porttitor ante, eu dignissim justo tortor nec mauris.

Level 5 Heading

Level 5 headings will begin on the same line of the paragraph that makes up the section. It will be indented 0.5", much like a normal paragraph indent. The heading will be in title case and bold italic font with a period at the end of the heading:

            Level Five Heading Here.   Start the first sentence of the paragraph that follows the heading on the same line and continue typing. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc at pellentesque massa. Sed nec urna nec est efficitur iaculis. Etiam efficitur velit id dignissim eleifend. Duis euismod, nisi sed cursus sodales, sem nisi porttitor ante, eu dignissim justo tortor nec mauris.

Table of Contents

Once you have added headings and used the styles feature, you will be able to use the word function to "generate" a table of contents. You will need to type "Table of Contents" in bold font, centered at the top of the page you will be inserting your table of contents onto. Then, place your cursor on the next line

From the References tab, click on Table of Contents and select Custom Table of Contents...

From the pop up window, you will want to change the tab leaders to (none) rather than the default. The rest of the default settings will be fine, so click ok once you've done so.

This will populate your table of contents.

From here, you will need to open the style pane to modify some of the formatting of the table of contents.

You will need to locate TOC 1 and click on it, and select "modify" from the drop down list.

TOC 1 style should be bold. If you've properly set up your "normal style" of font (see above), this should be the only modification to your TOC styles that you need to make. If the text is not properly set up and you need to further format it, you can do so from this window.

If set up correctly, your table of contents should look like the image below.

MLA Format Sub-headings

If you would like to utilize subheadings (subtitles) in your research paper, it is a good idea to first check with your instructor to be 100% sure what subheading format he/she would like you to use.

Depending on how long your paper is, you will need either one level subheadings or several levels subheadings

One Level Subheadings:

Format : centered, capitalize the first letter but not the whole subtitle.

MLA Format One Level Subheading

*Visit this full  sample paper for ideas!

Multi-Level Subheadings:

If your paper has subtitles under subtitles, see the format below. Be sure to check with your instructor first if he/she agrees with this format before you decide to use it.

How to Create a Structured Research Paper Outline | Example

Published on August 7, 2022 by Courtney Gahan . Revised on August 15, 2023.

A research paper outline is a useful tool to aid in the writing process , providing a structure to follow with all information to be included in the paper clearly organized.

A quality outline can make writing your research paper more efficient by helping to:

• Organize your thoughts
• Understand the flow of information and how ideas are related
• Ensure nothing is forgotten

A research paper outline can also give your teacher an early idea of the final product.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Follow these steps to start your research paper outline:

• Decide on the subject of the paper
• Write down all the ideas you want to include or discuss
• Organize related ideas into sub-groups
• Arrange your ideas into a hierarchy: What should the reader learn first? What is most important? Which idea will help end your paper most effectively?
• Create headings and subheadings that are effective
• Format the outline in either alphanumeric, full-sentence or decimal format

There are three different kinds of research paper outline: alphanumeric, full-sentence and decimal outlines. The differences relate to formatting and style of writing.

• Alphanumeric
• Full-sentence

An alphanumeric outline is most commonly used. It uses Roman numerals, capitalized letters, arabic numerals, lowercase letters to organize the flow of information. Text is written with short notes rather than full sentences.

• Sub-point of sub-point 1

Essentially the same as the alphanumeric outline, but with the text written in full sentences rather than short points.

• Additional sub-point to conclude discussion of point of evidence introduced in point A

A decimal outline is similar in format to the alphanumeric outline, but with a different numbering system: 1, 1.1, 1.2, etc. Text is written as short notes rather than full sentences.

• 1.1.1 Sub-point of first point
• 1.1.2 Sub-point of first point
• 1.2 Second point

To write an effective research paper outline, it is important to pay attention to language. This is especially important if it is one you will show to your teacher or be assessed on.

There are four main considerations: parallelism, coordination, subordination and division.

Parallelism: Be consistent with grammatical form

Parallel structure or parallelism is the repetition of a particular grammatical form within a sentence, or in this case, between points and sub-points. This simply means that if the first point is a verb , the sub-point should also be a verb.

Example of parallelism:

• Include different regions, focusing on the different arguments from those against immunization

Coordination: Be aware of each point’s weight

Your chosen subheadings should hold the same significance as each other, as should all first sub-points, secondary sub-points, and so on.

Example of coordination:

• Include immunization figures in affected regions
• Illnesses that can result from the measles virus

Subordination: Work from general to specific

Subordination refers to the separation of general points from specific. Your main headings should be quite general, and each level of sub-point should become more specific.

Example of subordination:

Division: break information into sub-points.

Your headings should be divided into two or more subsections. There is no limit to how many subsections you can include under each heading, but keep in mind that the information will be structured into a paragraph during the writing stage, so you should not go overboard with the number of sub-points.
