APA (American Psychological Association) is a way of citing references and organizing your academic writing. There are other different citation styles; however, APA is used mostly in the sciences and social sciences such as psychology, criminal justice, human services and business. You will use APA in a variety of ways throughout your academic career: term papers, research reports, literature reviews, articles, etc.
Here are the basic rules of formatting when it comes to APA papers; however, be sure to double check with your professor for the specifics of how your paper should be presented.

In-Text Citation Formats
You must use an in-text citation any time you use information from an outside source. This includes direct quotes, paraphrases, and summaries. When summarizing or paraphrasing, a page number does not need to be included in the in-text citation. See the chart below for format examples:
Author type | Parenthetical citation | Narrative citation |
---|---|---|
One author |
(Luna, 2020) |
Luna (2020) |
Two authors |
(Salas & D’Agostino, 2020) |
Salas and D’Agostino (2020) |
Three or more authors |
(Martin et al., 2020) |
Martin et al. (2020) |
Group author with abbreviation First citation Subsequent citations |
(NIMH, 2020) |
NIMH (2020) |
Group author without abbreviation |
(Stanford University, 2020) |
Stanford University (2020) |
When quoting directly from a source you must include the page number. For example:
If the quote is 40 words or longer use a block quote. Start the block quote on a new line, indent the entire quote a half-inch (as you would a normal paragraph), and omit the quotes:
Jones's (1998) study found the following:
Students often had difficulty using APA style, especially when it was their first time citing sources. This difficulty could be attributed to the fact that many students failed to purchase a style manual or to ask their teacher for help. (p. 199)
A list of references must be included at the end of your paper and includes publishing information for each source you have used in your paper.
The References page should:
Reference list entries include the four elements of the author, date, title, and source.
Here are some examples of the most common citation types. See the APA 7 Document Above, or the websites below for more information.
