Federalwide Assurances and IRB Registration

Penn operates under Federalwide Assurances (FWAs) in accordance Subpart A 46.103a which requires any institution engaged in non-exempt human subjects’ research, conducted or supported by HHS, to submit a written assurance of compliance to OHRP. Renewal is required every 5 years. Any updates made to the FWAs begins a new 5-year effective period.


All of the Penn IRBs listed under the FWAs are registered electronically in accordance with 45 CFR 46§501-505. Renewal of IRB Registration is required every 3 years. Any updates made to the IRB Registration begins a new 3-year registration period.


In certain circumstances, a funding agency or sponsor may request the FWA, institutional or IRB registration identifiers for Penn IRBs.
