This study analyzed how closely ChatGPT aligned with university IRB (institutional review board) decisions regarding which review category applies to research proposals. A literature review revealed that studies about IRBs mostly focus on ethical aspects of the process; this study offers additional insight into IRB administration. For this study, ChatGPT was asked to categorize 30 university IRB approved research studies as Standard, Expedited, or Exempt. Results indicated that ChatGPT review categorizations did not frequently align with university IRB categorizations. In this paper, ChatGPT responses to queries are shared, along with discussion about implications and concluding thoughts on how ChatGPT might be used to support IRB stakeholders.
