A majority of the membership of the IRB, which includes at least one non-scientific member, constitutes a quorum and is required in order to convene a meeting for the review of research protocols. Other business of the IRB may be conducted in the absence of a quorum. However, it is recommended that policy decisions of the IRB reached in the absence of a quorum should be ratified by the membership before being formally adopted.
A quorum requires that an IRB member whose concerns are primarily in nonscientific areas must be present at a convened meeting when research proposals are reviewed.
While it is not an absolute requirement that a quorum include the non-affiliated member(s), every effort should be made to encourage the non-affiliated member(s) to attend meetings. If necessary, alternate or additional non-affiliated members should be appointed.
