APA Formatting Checklist: Your Essential Guide to Flawless Papers

Getting your APA formatting right can feel like a puzzle. It's not just about citations; it touches everything from your title page to your reference list. A consistent and correct format makes your work easier to read and demonstrates your attention to detail. This checklist breaks down the key elements of APA style, so you can approach your next paper with confidence.

Title Page

The title page is your paper's first impression. It needs to be clear, concise, and contain specific information.

  • Title: Centered, bolded, and placed in the upper half of the page. Capitalize major words.
  • Author's Name: Your full name.
  • Institutional Affiliation: The university or college you're attending.
  • Course Number and Name: Example: PSY 101: Introduction to Psychology.
  • Instructor's Name: As provided by your professor.
  • Assignment Due Date: Format as Month Day, Year (e.g., October 26, 2023).
  • Page Number: The title page is page 1. It should be in the top right corner of the header.

Running Head

The running head is a shortened version of your title (50 characters or less, including spaces) and appears on every page.

  • For Professional Papers: Include "Running head:" followed by your shortened title in all caps.
  • For Student Papers (APA 7th Edition): Omit "Running head:". Just include the shortened title in all caps.
  • Placement: In the header, aligned to the left.
  • Page Number: In the header, aligned to the right.

Abstract

The abstract is a brief summary of your paper, typically 150-250 words.

  • Placement: On a new page, immediately after the title page.
  • Heading: "Abstract" (bolded and centered).
  • Content: A single paragraph summarizing your research question, methods, results, and conclusions. Do not indent the abstract paragraph.
  • Keywords (Optional): If requested, add "Keywords:" (italicized and indented) followed by your key terms, also italicized.

Main Body

This is where the bulk of your research and writing happens. Attention to detail here is crucial for clarity and credibility.

Headings

APA uses a clear hierarchy for headings to organize your content.

  • Level 1: Centered, Bold, Title Case Heading.
  • Level 2: Flush Left, Bold, Title Case Heading.
  • Level 3: Flush Left, Bold Italic, Title Case Heading.
  • Level 4: Indented, Bold, Sentence case heading, ending with a period.
  • Level 5: Indented, Bold Italic, Sentence case heading, ending with a period.

Example Structure:

Introduction

Literature Review

Previous Studies on Topic X Previous Study A Findings

Methodology

Participants Demographics. Participants were recruited from introductory psychology courses. Materials Questionnaires. The study utilized a standard demographic questionnaire. Procedure Data Collection. Data was collected over a two-week period.

In-Text Citations

Proper in-text citations give credit to your sources and allow readers to find them in your reference list.

  • Parenthetical Citation: (Author, Year) or (Author1 & Author2, Year).
  • Narrative Citation: Author (Year) stated that...
  • Direct Quotes: Include the author, year, and page number. Example: (Smith, 2020, p. 45). If the quote is 40 words or longer, it should be a block quote, indented 0.5 inches from the left margin, without quotation marks.
  • Multiple Authors:

Two authors: (Smith & Jones, 2021) or Smith and Jones (2021). Three or more authors: (Adams et al., 2019) or Adams et al. (2019).

  • No Author: Use the title of the work (shortened if long) and the year. Example: ("Understanding APA," 2022).
  • No Date: Use "n.d." for no date. Example: (Brown, n.d.).

Numbers and Statistics

  • General Rule: Use numerals for numbers 10 and above, and spell out numbers below 10.
  • Exceptions: Use numerals for statistics, percentages, measurements, and when comparing numbers. Example: There were 3 participants in the first group and 15 in the second.
  • Percentages: Use the % symbol. Example: 75%.
  • Hyphens: Use hyphens for compound adjectives before a noun. Example: a well-known study.

Tables and Figures

  • Placement: Tables and figures should be placed as close as possible to where they are first mentioned in the text.
  • Numbering: Number tables sequentially (Table 1, Table 2) and figures sequentially (Figure 1, Figure 2).
  • Titles: Give each table and figure a clear, descriptive title (bolded and in title case for tables, bolded and in title case for figures).
  • Notes: Use notes below tables and figures to explain abbreviations, symbols, or provide copyright information.
  • Referencing: Refer to tables and figures in the text by their number (e.g., "As shown in Table 3...").

Reference List

This is a critical section that provides full details for every source cited in your paper.

  • Placement: On a new page after the main body.
  • Heading: "References" (bolded and centered).
  • Order: Alphabetical by the first author's last name.
  • Formatting:

Hanging Indent: The first line of each reference is flush left; subsequent lines are indented 0.5 inches. Double-Spacing: The entire reference list should be double-spaced.

  • Key Elements for Common Source Types:

Journal Article: Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, volume(issue), pages. DOI (if available) Example: Grady, J. S., Her, M., Moreno, G., Perez, C., & Yelinek, J. (2019). Emotions in storybooks: A comparison of storybooks that represent ethnic and racial groups in the United States. Psychology of Popular Media Culture, 8*(3), 207–217. https://doi.org/10.1037/ppm0000185

Book: Author, A. A. (Year). Title of book. Publisher. Example: Strunk, W., Jr., & White, E. B. (1979). The elements of style*. Macmillan.

Chapter in an Edited Book: Author, A. A., & Author, B. B. (Year). Title of chapter. In C. C. Editor & D. D. Editor (Eds.), Title of book (pp. pages). Publisher. Example: Aron, L. (2016). Psychoanalytic theory. In I. B. Weiner & W. E. Craighead (Eds.), The handbook of clinical psychology* (5th ed., Vol. 1, pp. 25–45). John Wiley & Sons.

Webpage on a Website: Author, A. A. or Name of Group. (Year, Month Day). Title of specific page. Site Name. URL Example: National Institute of Mental Health. (2023, January 12). Anxiety disorders*. U.S. Department of Health and Human Services. https://www.nimh.nih.gov/health/topics/anxiety-disorders

Final Review

Before submitting, give your paper a thorough read-through.

  • Consistency: Check that all citations match the reference list and vice-versa.
  • Formatting: Ensure margins are 1 inch, font is readable (e.g., Times New Roman 12pt, Arial 11pt), and spacing is double.
  • Proofread: Look for typos, grammatical errors, and awkward phrasing.

Common Pitfalls to Avoid

  • Incorrect capitalization in titles: Always follow title case rules for main titles and subtitles.
  • Missing DOIs or URLs: Especially for online sources, these are crucial.
  • Inconsistent indentation: Ensure both in-text citations (for block quotes) and the reference list use correct indentation.
  • Forgetting the page number on the title page: It’s page 1, but it’s often overlooked.
  • Citing sources not used: Only include sources you've actually referenced in your text.

By systematically working through these points, you can significantly improve the presentation and academic rigor of your work.

Frequently Asked Questions

What is the most common mistake students make with APA formatting?

Students often struggle with the correct formatting of the reference list, including hanging indents, capitalization, and including all necessary publication details like DOIs.

How should I format a direct quote longer than 40 words in APA?

Longer quotes (block quotes) should be presented as a separate, indented paragraph (0.5 inches from the left margin) without quotation marks. Include the author, year, and page number in your citation.

Do I need a running head for student papers in APA 7th edition?

No, for student papers in APA 7th edition, you no longer need to include "Running head:" on the title page or subsequent pages. Just the page number is required.

How do I cite a source with no author or no date?

If a source has no author, use the title of the work (shortened if necessary) in place of the author's name. For no date, use "n.d." (no date) in place of the year.
