Single IRB (sIRB) and external IRB are terms used to reference a legal arrangement allowing IRB regulatory review and oversight of a study by one IRB when multiple institutions have jurisdiction for the same research protocol (this is called “reliance”). Most federally funded multi-site or cooperative research requires the designation of a single IRB to serve as the reviewing IRB for all participating sites.
Visit our Reliance and Navigation page for more information about reliance agreements and the team that assists researchers with collaborative and multi-site research issues.
Reliance Request: Relying on Another IRB
Reliance refers to the use of an institutional review board (IRB) outside of the University of Wisconsin-Madison (external IRB) to conduct the regulatory review and oversight of a study. Approval to rely on an external IRB requires an administrative review by HRPP including submitting a new study request in ARROW and execution of a reliance agreement.
Requests to rely on an external IRB are reviewed on a case-by-case basis. Various factors are considered in determining eligibility to rely on an external IRB such as risk level of study and whether the other institution is accredited.
Request Use of an External IRB
