What must an REB composition include under TCPS 2?

• A. A multidisciplinary mix with subject-matter expertise, community representation, and independence from the research team.
• B. Members appointed by the sponsor only.
• C. A rotating chair from the research team.
• D. No community representation required.

Answer: (A)

The essential idea is that an REB must be diverse, include community perspectives, and operate independently of the researchers. TCPS 2 requires a mix of expertise across disciplines so the board can evaluate scientific design, ethical considerations, and regulatory issues. It also mandates community representation to bring in values and concerns from those who could be affected by the research. And it calls for independence from the research team, meaning at least some members are unaffiliated with the study to prevent conflicts of interest and maintain objective review. This combination—multidisciplinary input, community voice, and unconflicted status—best aligns with how REBs are designed to function. The other options would undermine independence or exclude community input, which TCPS 2 does not allow.
