FAQ: How long does my IRB approval last?

Institutional Review Board (IRB) approval is valid for a maximum period of one year, with limited exceptions specified in the Human Research Protection Program (HRPP) Manual Section 8-8, “Demonstration Projects.” The approval period will be listed on approval letters sent to researchers, including both the approval date and the expiration date. Like initial approval, renewed approval is typically for a maximum of one year.  

Principal investigators who would like to continue human research activities, including data collection and/or analysis of identifiable private data, beyond the expiration of IRB approval must submit and receive renewed approval prior to the IRB project's expiration.

More information can be found in the HRPP Manual Section 8-7, Renewed Approval.
