APA Citation Guide for Students (7th Edition): In-Text & References
APA style is the citation format required by most psychology, education, nursing, and social-science courses, and the current standard is the 7th edition, published in 2020. This guide covers the two things you actually need to get right — in-text citations and the reference list — with copy-ready examples for the sources students cite most. Get these patterns down and you will stop losing easy marks to formatting errors.

What APA style is (and why it matters)
APA (American Psychological Association) style standardizes how you credit sources so any reader can find them and so you avoid accidental plagiarism. Citations come in two linked parts: a brief in-text citation in the body of your paper, and a full entry in the reference list at the end. Every in-text citation must have a matching reference, and vice versa — mismatches are the most common point-losing error professors flag. A clean reference list signals care; a messy one signals a rushed paper even when the argument is strong.
In-text citations: the author–date system
APA uses the author–date format. There are two ways to do it:
- Parenthetical: the author and year sit in parentheses at the end of the sentence. Example: Reading speed improves with practice (Smith, 2021).
- Narrative: the author’s name is part of the sentence and only the year is in parentheses. Example: Smith (2021) found that reading speed improves with practice.
Add a page number for direct quotes: (Smith, 2021, p. 14). For two authors, join with an ampersand in parentheses — (Smith & Lee, 2022) — but “and” in narrative form. For three or more authors, use the first author plus “et al.” from the very first citation: (Smith et al., 2023).
The reference list: format rules
Your references go on a new page titled References (centered, bold), with entries in alphabetical order by the first author’s surname and a hanging indent (the first line flush left, later lines indented). The four building blocks of almost every entry, in order, are: Author. (Year). Title. Source.
Journal article
Author, A. A., & Author, B. B. (Year). Title of the article. Title of the Journal, Volume(Issue), pages. https://doi.org/xxxx
Example: Garcia, M., & Patel, R. (2022). Sleep and academic performance in undergraduates. Journal of College Health, 70(4), 512–520. https://doi.org/10.1000/jch.2022.0456
Book
Author, A. A. (Year). Title of the book (edition). Publisher.
Example: Brown, T. (2021). Writing for psychology (2nd ed.). Academic Press.
Website / web page
Author, A. A. (Year, Month Day). Title of the page. Site Name. URL
Example: World Health Organization. (2023, March 15). Adolescent mental health. WHO. https://www.who.int/…

Title page and formatting basics
A student APA paper uses 1-inch margins, a readable 11–12 point font, double spacing throughout, and a page number in the top-right of every page. The student title page includes the paper title, your name, the course, the instructor, and the due date — centered in the upper half of the page. APA 7 dropped the running head requirement for student papers, a change many students still get wrong because they learned the 6th-edition rules.
Avoiding plagiarism with good citation habits
Correct citation is your first defense against a plagiarism accusation. Quote exactly and cite the page; paraphrase in genuinely your own words and still cite the source; and never reuse your own past work without permission (self-plagiarism is real). Before you submit, run your paper through the plagiarism and AI checker and review the deeper traps in our guide on how to avoid plagiarism. For any edge case this guide does not cover, the authoritative free reference is the Purdue Online Writing Lab, which has maintained the most-used APA guide for over 25 years.
Format your citations automatically
You can format every reference by hand using the patterns above, or LightspeedGhost’s AI essay writer generates correctly formatted APA, MLA, Chicago, and Harvard citations as it drafts — and keeps your in-text citations in sync with the reference list. You still verify each source is real and says what you claim, but you skip the tedious formatting. Working in another style?

Frequently asked questions
What APA edition should I use in 2026? The 7th edition, published in 2020, is the current standard. Confirm with your instructor, but unless told otherwise, use APA 7.
How do I cite a source with no author? Move the title to the author position: use the first few words of the title in the in-text citation, e.g., (“Adolescent Mental Health,” 2023).
How do I cite three or more authors in APA 7? Use the first author’s surname plus “et al.” from the first citation onward: (Smith et al., 2023). This is a change from older editions.
Do I need a page number for every citation? Only for direct quotes (and it is encouraged for specific paraphrased facts). General paraphrases need just the author and year.
What’s the difference between a reference list and a bibliography? A reference list includes only the sources you actually cited; a bibliography may list everything you consulted. APA uses a reference list.
