When should I use “et al.” in APA in-text citations?

Depending on the number of authors a source has, an APA in-text citation is shortened by using “et al.” (meaning “and others”) after the first author’s name.

Sources with 3–5 authors are written in full the first time and shortened from the second citation onwards. Sources with 6+ authors are always shortened, even the first time.

  • First in-text citation: (Taylor, Kotler, Johnson, & Parker, 2018)
  • Subsequent in-text citation: (Taylor et al., 2018)
