Review Categories & Timeline

The IRB will operate on significantly reduced hours over spring break and will not process any new applications until the first two weeks of the spring quarter. Thank you for your patience as we work through very high volume with limited staffing. We will process all applications in order of submission; the IRB cannot inequitably adjust processing to accommodate last-minute applications.
