MLA & APA: Citing Your Sources

The Apply Conventions rows on the IRR and IWA reward one thing above all: a consistent style, used accurately, with every in-text citation matched to the bibliography. Pick MLA or APA, then use it everywhere. This guide is built on the Purdue Online Writing Lab (Purdue OWL), the gold standard reference for both styles, including its annotated MLA and APA sample papers, which are linked below so you can see a correctly formatted paper from title to bibliography.

MLA 9th Edition

The default in English and the humanities. Author-page in-text citations and a Works Cited list.

In-text: (Panwar 4) or, with the author named in the sentence: According to Rajat Panwar, ... (4).

No page numbers (most websites): (Panwar) or just the author named in your sentence.

Works Cited entry (web article):
Panwar, Rajat. "Why Getting Someone's Name Right Matters." The Conversation, 12 Mar. 2023, theconversation.com/article-url.

Works Cited entry (journal article):
Author Last, First. "Article Title." Journal Name, vol. 12, no. 3, 2024, pp. 45-67.

APA

APA 7th Edition

The default in the social sciences and sciences. Author-date in-text citations and a References list. A strong fit when your lens is scientific, medical, or economic.

In-text: (Panwar, 2023) or, with the author named: Panwar (2023) found that ...

Direct quote: (Panwar, 2023, p. 4).

References entry (web article):
Panwar, R. (2023, March 12). Why getting someone's name right matters. The Conversation. https://theconversation.com/article-url

References entry (journal article):
Author, A. A. (2024). Article title in sentence case. Journal Name, 12(3), 45-67.

Which one should I pick?

College Board does not require a specific style; it requires ONE consistent style used accurately. Most AP Seminar students use MLA because this is an English course. If your lens leans scientific or medical and your sources are mostly studies, APA will feel natural. Pick one on day one and never mix.

The three-way check

Before submitting: (1) every in-text citation has a matching Works Cited or References entry, (2) every entry is actually cited somewhere in the text, and (3) all entries follow the same style and format. Mismatches cap the Citations row at 1 or 2 points out of 3.

Citation generators

Tools like the citation buttons in databases get you 90% there, but they make formatting errors constantly: wrong capitalization, missing dates, mangled author names. Always check generated citations against the Purdue OWL example for that source type before pasting them in.

The basics: 12-point Times New Roman, double-spaced everywhere (no single spacing anywhere), 1-inch margins. No title page. In the header of every page, starting on page 1: your last name followed by the page number.

The first page heading, top left, double-spaced: your first and last name, your teacher's full name, the course name, and the date written MLA style: day, month spelled out, year (12 February 2026).

The title: centered, same 12-point font. Not bolded, not underlined, not italicized.

In-text citations: author and page with no comma between them, placed after the quote but before the period: (Danhof 5). If you cite the same source again before citing anyone else, the page number alone is enough: (128). Three or more authors: (Baker et al. 14).

Block quotes: required when a quote runs longer than four lines of your paper. Start on a new line, indent the whole passage half an inch, no quotation marks, and put the citation AFTER the end punctuation.

Small moves readers check: titles of books and journals are italicized; quoting a source with an error means copying it exactly and following it with [sic]; omitted words become an ellipsis with spaces ( . . . ).

Works Cited: starts on a new page, title centered and unformatted. Alphabetical order, double-spaced, hanging indent (every line after the first indented half an inch). Include URLs for online sources, dropping the http://.

The title page (student version): the title in bold, centered, title case, three to four lines below the top margin. Below it: your name, then your department and school, the course number and name, your teacher's name, and the due date. Page numbers start on the title page and run on every page; student papers do NOT need a running head, abstract, or keywords.

Page one of the text: repeat the title, bolded and centered, above your first paragraph. No "Introduction" header.

Headings: Level 1 headings (Literature Review, Methods, Discussion) are centered, bolded, title case. Level 2 are flush left and bolded. Most student papers never need more than these.

In-text citations are author-date: (Theall, 2017). Direct quotes add the page: (Pounder, 2007, p. 178). Two authors use an ampersand: (Remmers & Brandenburg, 1927). Three or more authors use et al. from the first citation: (Boring et al., 2017). Multiple sources in one parenthetical are alphabetical and separated by semicolons.

Block quotes: required at 40+ words. Indent the whole passage half an inch, no quotation marks, citation after the final punctuation.

References: starts on a new page, the word References bolded and centered. Alphabetical, double-spaced, hanging indent. Include the DOI or stable URL whenever one exists.

Numbers rule worth knowing: spell out zero through nine, use numerals for 10 and up, with exceptions like percentages and dates, which are always numerals.

The most common conventions mistakes "Studies show..." with no attribution. In-text citations that never appear in the bibliography. Mixing MLA and APA in the same paper. URLs pasted as citations with no author, title, or date. Each of these is visible to a College Board reader in seconds.
