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.

Congratulations! You've successfully navigated a complex process and demonstrated that your research is well-designed and ethically sound.

IRB approval is good for one year from the date of your approval letter. As Principal Investigator, you have a few ongoing responsibilities to the IRB. You must:

  • notify the IRB if you want to change your research methods or location during the one-year approval period
  • apply for an extension if you need a bit more time than one calendar year to complete your project
  • apply for renewal if your project will run for another year
  • submit a status report for your project to date if you want to renew or extend a project beyond the one-year approval period
  • keep all documentation related to the project, including signed consent forms, for at least four years from the approval date (if you are a student, arrange this with your advisor)
  • keep any publications resulting from your research for at least four years from the approval date (if you are a student, arrange this with your advisor)

Best of luck with your research!
