What ensures that each individual involved in conducting a trial is qualified by education, training, and experience to perform their task?

• A. Education, training, and experience.
• B. Length of employment with the sponsor.
• C. Number of trials previously conducted.
• D. Self-certification of competency.

Answer: (A)

Qualification of trial personnel is ensured by confirming they have education, training, and experience appropriate to their tasks. This is required by GCP to ensure the person can perform their duties while protecting participants and ensuring data integrity. Education provides baseline knowledge; training covers the specific protocol, SOPs, safety requirements, and data collection procedures; experience shows they can apply this knowledge in real trial settings. Longer tenure, number of trials, or self-certification don't guarantee the necessary combination of knowledge and skills, so they are not sufficient to establish qualification.
