Proficiency Testing Provider

Accreditation Program

A2LA's accreditation program for Proficiency Testing Providers is designed for providers of proficiency testing schemes who wish to demonstrate their competence by formal compliance with a set of internationally-acceptable requirements for the planning and implementation of proficiency testing programs. The program will also provide users of proficiency testing programs (laboratories, accreditation bodies, regulators, technical assessors, etc.) increased confidence that the programs being relied upon are being operated competently in accordance with specified technical and management system requirements.

A2LA has been offering accreditation to proficiency testing providers for over a decade as demonstrated by our first accreditation, granted in December 2000.

Accreditation Requirements

Proficiency Testing Providers are assessed against the general criteria found in ISO/IEC 17043:2010 General Requirements for Proficiency Testing.
