Do all research require full review and approval by the IRB?
No. Some protocols, because of the nature of the research involved, are exempted by the federal regulations for full IRB approval. Exempt does not mean the protocols will not be reviewed by the IRB, only that these protocols will not be reviewed by the full committee. The IRB makes the final decision on whether a proposal falls under the exempt category. In addition, there are expedited reviews for certain kinds of low-risk research.
