The Institutional Review Board (IRB) is a committee that protects the rights and welfare of human research subjects by reviewing research projects for ethical implications. Researchers from the Park University community must have their research involving human participants approved by the IRB, and the IRB evaluates applications based on principles such as voluntary and informed consent, anonymity, and potential harm. The application process includes various scenarios that determine if the project is exempt, expedited, or requires full review, with outcomes communicated via official letters.
