Which item is NOT an essential component of a standard IACUC protocol submission?

• A. Study objective.
• B. Animal species and numbers.
• C. Justification.
• D. Detailed scheduling of staff shifts.

Answer: (D)

The plan evaluated by IACUC focuses on what will be done and why, not on day-to-day operations. The essential parts are the study objective (what you’re trying to learn), the animal species and numbers (which animals will be used and how many to achieve meaningful results while supporting the 3Rs), and the justification (why animals are needed and why this approach, including consideration of alternatives). These elements drive the ethical and scientific justification of the work.

Detailed scheduling of staff shifts, while important for day-to-day management and ensuring supervision and safety, does not affect the ethical approval or scientific justification of the protocol. It’s enough to confirm that personnel performing procedures are qualified and appropriately trained; exact shift times are typically handled through institutional procedures rather than the protocol itself.
