How to Label Appendices in APA

The "Publication Manual of the American Psychological Association" provides a comprehensive formatting guide to students who use the APA style to organize, structure and present their research papers. Appendices are usually the last sections of a paper, following references and footnotes. Including appropriate appendices will make your paper complete. They are used to present unpublished tests or to describe complex equipment, stimulus materials or detailed demographic information of the sample of your study.

Determine the number of appendices you need to include in your paper. Each appendix should contribute to a single purpose. For example, if you want to present both lists of detailed demographic data and detailed description of a complex piece of equipment, you should separate them in two appendices.

Label the appendix by typing "Appendix," at the top of the page. If your paper has more than one appendix, label each appendix with a capital letter. For example, write "Appendix A," "Appendix B" an so on until you have letters for all of your appendices. Start a new page for each appendix. The order of the appendices should follow the order in which they are mentioned in the paper. Insert a title following each appendix.

Center the title of the appendix. It should also be in title font. Do not bold, underline or italicize the word "Appendix" or the title. The font used should be the same as the main text of the paper.

Number each appendix table, figure and equation with the letter of the appendix. For example, if two tables are presented in Appendix A, label the tables as "Table A1" and "Table A2." When a table constitutes the entire appendix, you do not need to label the table. The title of the appendix serves as the label in this case.
