Who must review and sign the semi-annual report?

The correct answer indicates that a majority of all IACUC members must review and sign the semi-annual report. This requirement is grounded in the belief that a semi-annual report reflects the collective input and oversight of the entire IACUC, ensuring that a diverse range of perspectives has been incorporated.

Involving a majority ensures that the report accurately represents the consensus of the committee, which is vital for maintaining transparency and ethical oversight in animal research practices. This collective endorsement helps assure compliance with institutional policies as well as federal regulations that mandate comprehensive review processes to protect animal welfare.

Each member’s input is crucial; therefore, having only the chair, a quorum, or all members present sign off could compromise the thoroughness and representational quality expected in such important documentation. The majority rule guarantees that the perspectives of all members are considered, providing a robust framework for the report's findings and recommendations.
