According to VA rules, who is mandated to serve as the Institutional Official (IO)?

The Institutional Official (IO) in the context of VA rules is typically the Facility Director. This individual is tasked with the ultimate responsibility for the institution's compliance with regulations regarding research involving animals, ensuring that the institution adheres to applicable laws, regulations, and ethical standards. The Facility Director is in a unique position to oversee all operations at the institution, which includes the animal care and use program, and therefore is the most appropriate choice for this role.

The other roles listed, while important within their contexts, do not typically hold the overarching authority required to act as the IO. The Veterinary Medical Officer focuses on overseeing the veterinary care and health of the animals, which is critical but does not encompass the broader compliance role of the IO. The Animal Program Coordinator manages day-to-day operations and the details of animal care protocols but does not usually hold the institutional authority necessary to fulfill the IO responsibilities. Lastly, while the Chief Executive Officer (CEO) is a high-level administrator, the position may not always engage directly with the specific regulatory and ethical duties associated with animal care more than the Facility Director would, given the latter's direct involvement with the institution's animal program.
