Can the IRB/IEC invite non-members for assistance?

• A. Yes, the IRB/IEC may invite non-members with expertise in special areas for assistance.
• B. Non-members may not participate in any capacity.
• C. Non-members may vote on decisions.
• D. Non-members may replace IRB/IEC members.

Answer: (B)

The important idea here is that IRB/IEC decisions are made by the appointed members of the committee. Allowing non-members to participate would introduce external influence into the deliberations and voting, which can undermine the committee’s accountability and the consistency of protections for research participants. The structure is meant to keep the decision-making process within the defined membership, with any specialized input handled through separate, formal channels outside the IRB/IEC’s voting process.

That’s why the best answer is that non-members may not participate in any capacity. It preserves the integrity and independence of the committee. Options that suggest inviting non-members for assistance, having them vote, or replacing members would undermine governance and accountability, which is why they aren’t appropriate.
