HRPP: Metrics

The Purdue Human Research Protection Program (HRPP) and associated Institutional Review Board (IRB) strive to assist the research community on the application and review processes associated with human research.

PERA allows the HRPP to provide the research community with meaningful metrics to establish mutual expectations between researchers and reviewers. We will continue to provide new metrics as they become available.

A review begins when a new protocol is submitted by the Principal Investigator AND all study members have confirmed CITI training in Human Research and ends when a final determination letter is issued by HRPP/IRB. The processing includes all of the following:

  • Verification of personnel and training – return if training is incomplete
  • Pre-review by a protocol analyst
  • Review by a designated reviewer, either a member of the HRPP staff or an IRB Chair or Member.
  • Response to clarifications from the analyst and designated reviewer. This is what you can control! Responding to clarifications thoughtfully, thoroughly, and promptly all help to ensure timely review.
  • Processing the final decision and determination letter
