No, all APA papers do not require a cover page. However, some instructors may request one for certain assignments and papers. Whether or not you are required to use a cover page will typically be stated in the assignment guidelines.
For papers that do require a cover page, the conventions for formatting this page are typically outlined in the APA Publication Manual (6th edition) guidelines or in any reference guide that outlines the paper formatting requirements for APA style. Typically, this page should appear first when submitting an APA paper and should include a concisely written title, name, course, and date. Additional items that may be included are the name of the professor and additional instructions.
You can find more information on the basics of how to structure and write a cover page for your APA paper, including detailed instructions and examples on the Purdue OWL website: https://owl.purdue.edu/owl/research_and_citation/apa_style/apa_formatting_and_style_guide/general_format.html .
It is also important to note that any figure or image included in your paper would need to be numbered separately from page numbers, as they are typically presented in a separate section at the end of the paper.
The key takeaway is to check the assignment instructions to see if a cover page is required and, if so, look to the Publication Manual for the details on how to format the message. Good luck with your assignments!
