Which statement best describes the purpose of proficiency testing in forensic labs?

• A. To assess general lab safety compliance.
• B. To verify technicians’ abilities through regular blind testing.
• C. To publicly compare labs' performance.
• D. To measure overall lab productivity.

Answer: (B)

Proficiency testing measures how well lab personnel can accurately process and interpret forensic analyses under conditions where they don’t know they’re being tested. Regular blind samples are sent to the lab, and the results are compared to the true values to reveal real-world performance, including any gaps in training or procedure adherence. This focuses on the competency and reliability of the people doing the work, not just the processes themselves. This isn’t primarily about safety inspections, public rankings of labs, or how fast work gets done. While those are important, proficiency testing specifically targets whether technicians and the lab can produce correct, defensible results in challenging or routine cases, which is essential for maintaining accreditation and courtroom reliability.
