how to write appendices
APA 7 addresses appendices and supplemental materials in Section 2.14 and on page 41:
- The appendices follow the reference list.
- They are lettered “Appendix A,” “Appendix B,” “Appendix C,” and so forth. If you have only one appendix, however, simply label it Appendix.
- Put figures and tables in separate appendices. The appendix title serves as the title for a table if it is the only table in the appendix.
- If you decide that certain figures and tables should appear in the same appendix, number them A1, A2, A3, and so forth, according to the appendix in which they appear.
- The materials in the appendix must not extend beyond the margins of the rest of the paper: Reduce the appendix materials as needed.
All information, methods, data, diagrams and maps, whether obtained or based on the work of others, must be acknowledged using one of the referencing styles recommended for engineering. To learn more, see Academic integrity or the Citing and referencing Library guide.
Appendices contain material that is too detailed to include in the main report, such as long mathematical derivations or calculations, detailed technical drawings, or tables of raw data. The content should be summarised and referred to at the appropriate point in the the body of the report. The conventions for appendices are as follows:
Talk to your advisor if you have material that you are not certain about. They should be able to provide guidance about what should be included in an Appendix. Also, consult your chosen style guide about and appropriate content and formatting considerations.
Letters receiving permission to reproduce or adapt images, instruments for research, or other copyrighted materials.(See Copyright section of this website)

The APA Publication Manual does not give explicit direction on how to cite external sources that are used within appendices. However, APA style favors the idea of keeping all sources cited in a single reference list. A good practice would be to cite your source information in your appendix with an in-text parenthetical citation, like you would in the body of your paper, and include the source in the alphabetical list with everything else in your References section. With a grey area like this, where the manual does not have explicit direction, it is often a good idea to check in with your instructor to ensure that your approach will align well with their expectations.
