If you do not have access to an Institutional Review Board at your institution, there are several potential solutions, including:
- Partner with another institution that has one and that is willing to have it serve as the IRB of record for the study.
- Use an external, commercial one, such as Solutions IRB (https://www.solutionsirb.com).
- Start an IRB.
