IRB exempt vs full review category, and how does it affect research timelines?

• A. Exempt means no ethics review is needed.
• B. Exempt/expedited involve minimal risk or faster review; full board review requires comprehensive review and longer timelines.
• C. Full board review is faster than expedited.
• D. Exempt category takes longer than full review.

Answer: (B)

Risk level and oversight scope determine how quickly a study moves through IRB. When a project is judged to involve minimal risk and fits exempt criteria, the review is usually handled by the IRB chair or a small subset of members, or it’s simply an exemption determination. This leads to a faster process because there’s less formal review required and no need for a convened full board meeting. Expedited review likewise aims for minimal-risk studies but involves a small panel of reviewers, keeping the process quicker than a full board. Full board review, on the other hand, requires a convened IRB meeting with full discussion and approval, plus potential revisions, which makes the timeline longer. So exempt or expedited reviews tend to be faster, while full board reviews require more time due to the more thorough, group oversight.
