The APA manual does not have a section on how to format a PowerPoint presentation, but you can follow APA style guidelines within your PowerPoint. For example:
How to cite PowerPoint slides in your References List
You will use the following format to cite PowerPoint slides:
Author, A. A. (year). Title of presentation [PowerPoint slides]. Website Name. https://xxxxx
Please note that “if the slides come from a classroom website, learning management system [e.g., Blackboard], or company intranet and you are writing for an audience with access to that resource, provide the name of the site and its URL (use the login page URL for sites requiring login)” (APA, 2020, p. 347). Don't forget to indent the second and subsequent lines.
Goodwin University. (n.d.). Social media and marketing communications: Written/Oral project outline. [PowerPoint slides]. Blackboard. https://goodwin.blackboard.com
