As per Section 2.14 of the APA Publication Manual, 7th edition, an appendix or appendices are included after the references, footnotes, tables, and figures of the paper. In other words, appendices are the last item in your paper. Each appendix should be separately mentioned within the main text (e.g., “see Appendix A”). Appendices are to be self-contained; they should describe the contents and clearly have a label and title.
