The minimum number of members required on an Institutional Review Board (IRB) or Independent Ethics Committee (IEC) is five. This requirement is set to ensure a diverse and comprehensive perspective when reviewing research proposals. An IRB or IEC with at least five members can provide a balanced evaluation of the ethical aspects of a study, considering various viewpoints, including scientific, medical, and ethical perspectives. The inclusion of members from different backgrounds and disciplines is crucial to safeguard the rights and welfare of research participants, promote fairness, and uphold the integrity of the research process. In addition, having multiple members helps facilitate thorough discussions and better decision-making in committee meetings.
