The American Psychological Association (APA) is the leading professional organization in the US that promotes advancement in the psychology field.  APA offers a variety of resources, publications, and standards for research, writing, and professional practice. 

Students often encounter APA when asked to complete academic writing assignments in APA style, which is frequently utilized across disciplines such as business, healthcare and nursing, informatics and IT, social work, and many others.

APA In-Text Citations

Writers use in-text citations (sometimes called parenthetical citations) to give credit to quoted, paraphrased, or summarized source material. In APA style, there are three required pieces of information to include in an in-text citation:

  1. Author's last name
  2. Year of source's publication
  3. Page number of cited material (if applicable, or appropriate substitute)

How these pieces of information are formatted in an essay depends on whether or not the writer uses a signal phrase to introduce the upcoming source, as shown in the examples below.
