IRB Estimated Review Times

Below you can find estimated review times, to give you an idea of how long it usually takes the IRB to review submitted protocols. Review does not begin until the application is fully complete, including all authorizing signatures. Be aware that these time periods only serve as a general guidance; depending on the situation, they can be subject to change and there is no guarantee of accuracy for an individual project.
