Which of the following entities does NOT report directly to the IO?

The Institutional Board of Trustees typically has overarching governance responsibilities for the institution but does not directly report to the Institutional Official (IO) in the context of the IACUC and animal care and use programs. The IO is responsible for overseeing the animal care program and ensuring compliance with federal regulations and institutional policies, but the Board of Trustees is not involved in the day-to-day operational aspects or direct reporting structures related to the IACUC.

In contrast, the attending veterinarian, IACUC, and compliance office all have specific roles that involve regular communication and reporting to the IO regarding animal welfare, regulatory compliance, and overall program management. The attending veterinarian is responsible for the health and wellbeing of the animals and must report any issues directly impacting animal care. The IACUC oversees the ethical and humane use of animals in research and reports findings and recommendations to the IO. The compliance office monitors adherence to regulatory standards and assists in ensuring that practices align with institutional policies, thereby also maintaining a direct line of reporting to the IO.
