A research assistant on a study was recently promoted to a clinical research coordinator (CRC)...

The regulatory binder (investigator site file) must contain documents verifying qualifications of all personnel. These include curricula vitae (CVs), professional licenses, and training certificates.

ICH E6(R2) 4.1.5: “The investigator should ensure that all persons assisting with the trial are qualified by education, training, and experience… Current curriculum vitae and/or other relevant documents evidencing qualifications should be maintained.”

21 CFR 312.53(c)(1): Sponsors must select investigators qualified “by training and experience,” and investigators must provide sufficient documentation, typically updated CVs.

Letters of promotion (A), training brochures (B), or performance reviews (C) may remain in personnel files but are not required regulatory documents. The only acceptable regulatory proof is an updated CV (D), which reflects the individual’s training and qualifications for their new role.

Therefore, the correct answer is D (Updated CV). This ensures compliance with ICH and FDA requirements for staff qualification documentation in clinical research.
