Quick overview before we hit the examples

APA heading levels are just a hierarchy system. They show your reader what’s a main section, what’s a subsection, and what’s a tiny detail tucked inside a subsection. The magic happens when you see real examples of APA format heading levels in context, so we’ll spend most of this guide walking through realistic paper excerpts.

All examples below follow APA Style, 7th edition, which is still current in 2024–2025. You can always double-check details against the official APA Style site at apastyle.apa.org.

Example of APA heading levels in a short student paper (Levels 1–2)

Let’s start simple: a typical undergraduate paper with only Level 1 and Level 2 headings. Imagine a psychology paper titled The Impact of Social Media on Sleep in College Students.

Here’s how the heading structure might look on the page:

Title page (centered, bold, Title Case)
The Impact of Social Media on Sleep in College Students

On the first page of text, you repeat the title at the top, centered and bold. That title acts like a Level 1 heading for the whole paper.

Level 1 (centered, bold, Title Case)
The Impact of Social Media on Sleep in College Students
Text begins as a regular paragraph, indented.

Now you add main sections. These are also Level 1 headings:

Level 1 examples include:
Literature Review
Text begins as a regular paragraph, indented.

Method
Text begins as a regular paragraph, indented.

Results
Text begins as a regular paragraph, indented.

Discussion
Text begins as a regular paragraph, indented.

Within the Method section, you might need subsections. Those use Level 2 headings.

Method
Text introducing the method.

Participants
Text about who took part in the study.

Measures
Text explaining surveys, scales, or tools.

Procedure
Text describing what participants did.

This is one of the best examples of a simple APA heading setup: just Level 1 for main sections and Level 2 for subsections. Many first- and second-year college papers never need more than this.

Real examples of APA format heading levels for a full research report (Levels 1–3)

Now let’s expand to Level 3 headings, which you’ll often see in more detailed research projects, theses, or capstone papers.

Imagine a paper titled Online Learning Fatigue Among High School Students. Here’s a realistic structure using Levels 1–3.

Level 1 headings (centered, bold)
Online Learning Fatigue Among High School Students
Introduction
Method
Results
Discussion

Within Method, you might use Level 2 headings:

Method
Introductory paragraph.

Participants
Text about demographics and recruitment.

Measures
Text describing surveys and scales.

Procedure
Text describing the steps of the study.

Now suppose your Measures section is getting long. You can break it down further with Level 3 headings.

Measures
Introductory sentence.

Online Learning Fatigue Scale. Text describing this scale.

Perceived Stress Scale. Text describing this scale.

Sleep Quality Index. Text describing this measure.

Notice how Level 3 looks:

  • Left-aligned
  • Bold
  • Italic
  • Title Case
  • Text begins as a new paragraph on the next line

This is a clean example of how Level 1, Level 2, and Level 3 heading levels work together in a way that makes sense to a reader—and to your professor.

For official confirmation of these formats, you can compare these examples of APA format heading levels with the APA Style 7th edition sample paper from the American Psychological Association:

Detailed examples of APA format heading levels (Levels 1–5)

Most students never need Level 4 or 5, but if you’re writing a thesis, dissertation, or a very detailed project, you might. Let’s build a full five-level example of APA format heading levels using a hypothetical paper: Community-Based Interventions to Reduce Adolescent Vaping.

Level 1 heading example

Community-Based Interventions to Reduce Adolescent Vaping
Introductory text.

Method
Introductory text.

Level 2 heading example

Within Method, you create subsections:

Method
Introductory paragraph.

Participants
Text about age, location, recruitment.

Measures
Overview of questionnaires and interviews.

Procedure
Overview of how the intervention was delivered.

Level 3 heading example

Your Procedure section needs further breakdown:

Procedure
Introductory sentence.

Baseline Assessment. Text describing pre-intervention data collection.

Intervention Sessions. Text describing weekly group sessions.

Follow-Up Assessment. Text describing 3‑month follow-up.

Level 4 heading example

Within Intervention Sessions, you might have different formats that need their own headings. This is where Level 4 appears.

Intervention Sessions. Introductory sentence.

*Educational Workshops.* Text about classroom-style sessions.

*Peer-Led Support Groups.* Text about small-group discussions.

*Parent Information Nights.* Text about evening sessions for families.

Level 4 headings are:

  • Indented
  • Bold
  • Title Case
  • End with a period
  • Followed by text on the same line as the heading

Level 5 heading example

Now imagine that within Peer-Led Support Groups, you want to separate in-person and online formats. This is where a Level 5 heading fits.

*Peer-Led Support Groups.* Introductory sentence.

In-Person Groups. Text describing the face-to-face format.

Online Groups. Text describing the virtual format.

Level 5 headings are:

  • Indented
  • Bold
  • Italic
  • Title Case
  • End with a period
  • Text continues on the same line as the heading

This layered structure gives you one of the best examples of APA format heading levels from Level 1 through Level 5, all working together in a realistic research topic.

Side‑by‑side summary of heading level styles

To keep these examples of APA format heading levels easy to remember, here’s a quick text-based summary you can visualize as you write:

  • Level 1: Centered, bold, Title Case. Text starts as a new paragraph on the next line.
  • Level 2: Left-aligned, bold, Title Case. Text starts as a new paragraph on the next line.
  • Level 3: Left-aligned, bold, italic, Title Case. Text starts as a new paragraph on the next line.
  • Level 4: Indented, bold, Title Case, ends with a period. Text continues on the same line.
  • Level 5: Indented, bold, italic, Title Case, ends with a period. Text continues on the same line.

When in doubt, most student papers only need Levels 1 and 2. Levels 3–5 are there when your sections start to feel crowded and confusing without extra structure.

For another clear example of how researchers use heading levels in real life, you can skim open-access articles on PubMed Central and look at their section headings:

More real examples of APA format heading levels by discipline

Different subjects lean on headings in slightly different ways. Here are a few more real-world style examples of APA format heading levels you can adapt.

Education research paper example

Topic: Effects of Project-Based Learning on Middle School Science Achievement

Possible heading structure:

  • Project-Based Learning in Middle School Science (Level 1 – repeated title)
  • Literature Review (Level 1)
  • Method (Level 1)
    • Participants (Level 2)
    • Setting (Level 2)
    • Instructional Materials (Level 2)
    • Procedure (Level 2)
      • Teacher Training. (Level 3)
      • Implementation Timeline. (Level 3)
  • Results (Level 1)
  • Discussion (Level 1)

Nursing or public health paper example

Topic: Hand Hygiene Compliance Among Hospital Nurses

Heading structure example of APA format heading levels:

  • Hand Hygiene Compliance Among Hospital Nurses (Level 1 – repeated title)
  • Background (Level 1)
  • Method (Level 1)
    • Study Design (Level 2)
    • Participants (Level 2)
    • Data Collection (Level 2)
      • Direct Observation. (Level 3)
      • Electronic Monitoring. (Level 3)
    • Data Analysis (Level 2)
  • Results (Level 1)
  • Discussion (Level 1)

If you’re writing in health fields, you might like looking at real articles on CDC or NIH sites to see how professionals organize sections, even when they don’t follow APA headings exactly:

Social sciences paper example

Topic: Work-From-Home Satisfaction Among Parents of Young Children

Here’s another example of APA format heading levels with some Level 4 headings:

  • Work-From-Home Satisfaction Among Parents of Young Children (Level 1 – repeated title)
  • Introduction (Level 1)
  • Method (Level 1)
    • Participants (Level 2)
    • Measures (Level 2)
    • Procedure (Level 2)
  • Results (Level 1)
    • Descriptive Statistics (Level 2)
    • Predictors of Satisfaction (Level 2)
      • Work Environment Factors. (Level 3)
        • Dedicated Workspace. (Level 4)
        • Flexible Scheduling. (Level 4)
      • Family-Related Factors. (Level 3)
  • Discussion (Level 1)

These are the kinds of real examples that help you see when you might actually need Level 3 or Level 4 headings in practice.

Common mistakes to avoid when copying these examples

When students try to recreate examples of APA format heading levels, the same mistakes show up again and again. Here are the big ones to watch for:

Using headings instead of transitions.
Not every new idea needs a heading. If a paragraph is just continuing the same thought, a transition sentence works better than a new heading.

Skipping levels.
If you jump from Level 1 straight to Level 3, your outline becomes confusing. Always move down the ladder one step at a time: Level 1 → Level 2 → Level 3, and so on.

Styling headings like regular text.
Headings should stand out. Don’t center a Level 2 heading, and don’t italicize a Level 1 heading. Use the styles from the examples of APA format heading levels above.

Turning a single paragraph into its own heading.
If a “subsection” is just one short paragraph, consider whether it really needs a separate heading.

Overusing Level 4 and 5.
If your paper is fewer than 10–12 pages, you probably don’t need Level 4 or 5 at all. In most student assignments, Level 1 and 2 are enough, with the occasional Level 3.

If you want to see how professional writers balance headings and paragraphs, skim student and professional sample papers from APA:

In 2024 and 2025, a few patterns keep popping up in how students use APA heading levels:

  • More digital, multimodal topics. Papers on TikTok, AI, telehealth, and remote work often need extra subsections to keep the structure clear.
  • More group projects. Students use Level 2 or Level 3 headings to separate sections written by different team members while still keeping a unified paper.
  • More use of templates. Many learning management systems and university libraries now provide APA 7th edition templates with heading styles pre-set. These templates make it easier to apply the kind of examples of APA format heading levels you’ve seen here.

If your university library offers an APA template (often a .docx file), downloading it can save a lot of time. Libraries at schools like Harvard share guidance that aligns well with APA rules, even when they don’t provide a full template:

FAQ: Short answers with more examples

Q: Can you give a quick example of Level 1 and Level 2 headings in a basic APA paper?
Yes. Imagine a paper on exercise and mood:

  • Exercise and Mood in Young Adults (Level 1 – repeated title)
  • Introduction (Level 1)
  • Method (Level 1)
    • Participants (Level 2)
    • Measures (Level 2)
    • Procedure (Level 2)
  • Results (Level 1)
  • Discussion (Level 1)

This is one of the simplest and best examples of APA format heading levels for a standard assignment.

Q: Do I always need all five heading levels?
No. Many papers only use Level 1. A lot of undergraduate papers use Level 1 and Level 2. Levels 3–5 show up more in theses, dissertations, and long research projects.

Q: Where can I see more real examples of APA headings?
The APA Style website has sample student and professional papers that include headings. You can also look at open-access research articles in psychology, education, or nursing journals and notice how they structure their sections.

Q: Should my introduction have a heading?
In APA 7th edition, the introduction starts under the repeated title of your paper, which acts like a Level 1 heading. You don’t need to label it “Introduction” unless your instructor specifically asks for that heading.

Q: Are headings formatted differently in the reference list?
Yes. The reference list uses a simple Level 1 heading: References (centered, bold, Title Case). Individual references are not headings; they follow their own formatting rules.

If you keep these examples of APA format heading levels nearby while you write, you’ll start to see your paper as an outline on the page. Once the structure is clear, the writing itself gets much easier.
