Appendix sections are essential for presenting supplementary material that supports the main text. This could include raw data, detailed methodology, or extensive calculations. In the appendix in APA style, each section is labeled with a letter (e.g., Appendix A) and must be referred to in the main text. This structured approach ensures that additional information is easily accessible to readers, enhancing the clarity and depth of the research without cluttering the primary narrative.

What Is an Appendix?

An appendix is a section at the end of a document that provides supplementary information, such as raw data, detailed explanations, or additional resources. It supports the main text by offering extra details that are relevant but not essential to include within the main content.

General Appendix Format


  • Title the section “Appendix” if there’s only one.
  • If there are multiple, label them “Appendix A,” “Appendix B,” etc.


  • Provide a descriptive title for each appendix (e.g., “Appendix A: Survey Questionnaire”).


  • Appendices should appear in the order they are mentioned in the text.

Text Format

  • Begin each appendix on a new page.
  • Maintain consistent formatting with the main text (font, margins, etc.).


  • Include relevant supplementary material such as raw data, detailed methodology, charts, graphs, or additional explanations.
  • Each type of content should be clearly labeled and organized.


  • Cite any sources or references within the appendix according to the same citation style used in the main text.
