How long does IRB approval take?

The approval process can take several weeks, depending on whether you meet the submission deadline, the complexity of your project, the subjects you intend to work with, the completeness of your application materials, and other factors. Plan to submit your application at least three weeks before you want to start your research.


Submit your application as soon as it's ready! The IRB meets to review applications only once each month during the academic year. These deadlines are the latest dates you can submit an application for each month's meeting. But many proposals don't need review by the full committee—they're processed and approved throughout the month. In most cases, review takes about two weeks.

The IRB does not meet during the summer.
