Who is the best person to make decisions about animal care or technical interactions for a group of study animals?

• A. The Study Director
• B. The Principal Investigator
• C. The Veterinarian
• D. The Facility Supervisor

Answer: (A)

The main idea is that accountability for the study’s conduct, including animal care and who performs procedures, rests with the Study Director. This role oversees the entire study, ensuring that all animal care, handling, and technical interactions align with the protocol, regulations, and humane care standards. The Study Director decides what procedures are appropriate, what training and qualifications are required, and who may interact with the animals, integrating welfare considerations into every decision. The veterinarian provides medical care and welfare guidance, diagnosing and treating health issues, but does not sanction all care decisions for the group across the study. The Principal Investigator leads the scientific aspects of the study, but the overarching responsibility for animal care decisions and study conduct typically sits with the Study Director. The Facility Supervisor manages housing and facility operations, implementing approved protocols but not making the study-wide care decisions. Therefore, the best person to make decisions about animal care or technical interactions for a group of study animals is the Study Director.
