Appendix (Appendices)

According to the Publication Manual of the American Psychological Association, 7th ed., (APA Manual), authors may want to include material that supplements the paper's content but would be distracting or inappropriate in the text of the paper. A general rule of thumb is to include an appendix only if it helps readers understand, evaluate or replicate the study or theoretical argument being made. Follow the same ethical standards for copyright attribution, accurate representation of data, and protection of human participants. Generally, the appendix is appropriate for materials that are brief and easily presented in print format. Examples of material suitable for an appendix include:

  • lists of stimulus materials
  • instructions to participants
  • tests, scales, or inventories developed for the study being reported
  • text, tables, figures, or a combination
  • detailed demographic descriptions of subpopulations in the study
  • other detailed or complex reporting items


The appendix appears on a new page after the references, footnotes, tables and figures.

If you have more than one appendix, label the first appendix Appendix A, the second Appendix B, etc.

The appendix title should describe its contents.

Put the appendix label and title in bold and centered on separate lines at the top of the page.

The appendices should appear in the order that the information is mentioned in your essay.

Use title case for the appendix and label and title.
