What should the investigator provide evidence of?

• A. Their personal financial status.
• B. Their qualifications, including education, training, and experience.
• C. Their willingness to enroll participants.
• D. Their institution's accreditation.

Answer: (B)

The key idea is that investigators must demonstrate they are qualified to conduct the trial. In Good Clinical Practice, the investigator needs appropriate education, training, and experience to supervise the study and protect participants. Therefore, they should provide evidence of their qualifications—such as a current CV, professional licenses or certifications, and records of relevant training and experience—to the sponsor and the ethics committee before starting the trial. This documentation shows they can follow the protocol, manage safety reporting, and ensure data integrity. Personal finances, willingness to enroll participants, or the institution’s accreditation are not the primary evidence of the investigator’s qualifications.
