IRB Guidebook

The IRB Guidebook was last updated in 1993. Developments over the intervening years have made portions of the Guidebook information obsolete, while portions of the information remain valid. There is no errata document to indicate which information has been superseded. OHRP cautions users to verify the current validity of any Guidebook information before relying on the information in a program of human subjects protection.
