APA style requires the author, year and page for in-text citations:

(Author, date, page)

example:    (Smith, 2000, p. 20)

If the information you are citing is from more than one page you would use pp. instead of p. to indicate more than one page is being cited

Example: (Smith, 2000, pp. 23-24)

If you are citing a work that doesn't have pagination (such as a website) indicate which paragraph the information appears in by using para. for an abbreviation of the word paragraph.

            Example: (Thomas, 2015, para. 3)

If you are citing a work that has two authors you must list both last names

Example: (Jameson & Harris, 2003, p. 42)

If you are citing a work that has between three and five authors you must list all of the authors’ names the first time you cite the work.  Each subsequent time the work you need to provide the first author listed followed by an et al.

Example: 1st time citing a source with four authors 

(Parker, Sterling, Hodges & Taylor, 2015, p. 87)

Each additional citation would be (Parker et al., 2015, p. 87)

If you are citing a work that has six or more authors cite the last name of the first author followed by an et al.

Example: (Daly et al., 2010, p. 78)

If you are citing a work that is authored by a group (a government agency, corporation, non-profit association, think tank) you must type out the group name as it appears in the text

Example: (The Annenberg Foundation, 2014, par. 3)

If you are citing a work that doesn’t have a date of publication use n.d. (no date) in place of a date. 

Example: (National Health Institute, n.d., par. 4)

If you are citing a work that doesn't have an author you'll need to state part of the title in your in-text citation.  Make sure that the title is put in double quotes (" ").

Example: Below is the full citation for a webpage without a listed author.

State-by-State Effects of a Ruling for the Challengers in King v. Burwell. (2015). Retrieved June 1,

2015, from http://kff.org/interactive/king-v-burwell-effects/ 

The citation starts with State-by-State Effects of a Ruling for the Challengers in King v. Burwell

So the in-text citation would be ("State-by-State Effects", 2015, par. 2)

If you are citing a particular quote from a video or audio recording provide the time stamp of when the quote occurs:

             Example: (Ferris, 2008, 3:15)
