Which role is typically not filled by an IACUC member?

The role that is typically not filled by an IACUC member is the Institutional Official. The Institutional Official is responsible for the overall animal care and use program within the institution and is often a higher-level administrator, such as a university president or vice president. Their responsibilities include ensuring compliance with federal regulations and policies as well as overseeing the IACUC, but they do not actively participate as a voting member of the committee.

In contrast, the other roles mentioned are integral to the IACUC composition. A veterinarian with program responsibility provides veterinary care, advice, and oversight regarding animal welfare, while a scientist with animal experience brings valuable research insights and understanding of the scientific use of animals. The non-affiliated member serves to represent community interests and brings an external perspective to the committee's discussions, thus ensuring a balanced view of animal welfare considerations. Each of these roles contributes directly to the functioning of the IACUC and its mission to ensure ethical care and use of animals in research and education.
