Many study groups initiate protocols which use new technologies or treatment techniques. They want to ensure that the participating institutions understand the protocol and can treat patients according to protocol stipulations. Therefore, the IROC Houston has been asked on many occasions to develop and implement credentialing processes. Credentialing is or has been done for RTOG, GOG, NCCTG and NSABP. Credentialing involves proving adequate knowledge of the protocol, treatment planning system, and QA procedures. This is done through the use of questionnaires and one or more test cases. The approval may be for an institution, specific personnel, or both.
