In the complex process of assessing a facility’s competence, reviewing performance in proficiency testing (PT) has a significant place as a meaningful and helpful indicator. Proficiency testing supplements the internal quality control system of a facility, providing a means of external assessment of its testing or measurement capabilities. It is a valuable tool for facilities to compare their performance with that of the other participants in the same program. This in turn provides the opportunity to investigate any outlive results, identify the root cause of the problem and improve the performance where needed.
The benefits of proficiency testing are widely recognized. These include:
- Comparison of a facility’s performance with that of other participating facilities
- Monitoring of a long-term facility performance
- Improvement in the performance of tests/calibrations following investigation and identification of the cause of unsatisfactory PT performance, and the introduction of corrective action to prevent re-occurrence
- Staff education, training and competence monitoring
- Evaluation of methods, including the establishment of method precision and accuracy
- Estimation of measurement uncertainty
- Contribution to the facility’s overall risk management system
- Confidence building with interested parties, e.g. customers, accreditation bodies, regulators, specifies
