Which is an example of a QA measure?

• A. Peer review
• B. Proficiency testing
• C. Public disclosure
• D. Random auditing

Answer: (B)

QA measures in forensic work are about proving that the testing process is accurate and reliable. Proficiency testing does this in a clear, objective way: labs analyze blind samples whose true results are already known, and their results are compared against the correct answers. This external benchmarking shows whether the lab, its personnel, and its methods are performing correctly under real conditions. When scores reveal gaps, the lab can implement retraining, method adjustments, or process changes, which strengthens overall quality. That external, performance-based evaluation is the hallmark of a QA measure. Peer review is important for checking how conclusions are documented and reviewed within the team, but it doesn’t provide the standardized external performance benchmark that proficiency testing offers. Public disclosure isn’t a QA measure of testing accuracy, and random auditing, while useful, is more variable and less central to demonstrating consistent, validated performance like proficiency testing does.
