IRB review and approval is required for research projects involving human subjects.
Human subjects research is a systematic investigation (research question/hypothesis testing), designed to contribute to generalizable knowledge (add to the scientific knowledgebase in the field) done so while intervening or interacting with living individuals or their identifiable data. For additional information, please see our guidance on What is Human Research and watch our pre-recorded training video: Does Your Project Require IRB Review?
If you are still unsure whether or not your study is human subjects research, complete and submit the IRB Protocol for Determination of Human Research in eIRB.
