A local IRB is typically associated with a specific institution, such as a university, hospital, or research organization. It reviews research projects that are conducted within that institution’s jurisdiction. Researchers conducting studies at that institution must submit their research proposals to the local IRB for review and approval. Local IRBs are familiar with the specific research environment and resources of their institution, which can aid in making contextually relevant ethical decisions.
Generally, academic institutions use local IRBs because they conduct a lot of internal research.
