Accredited Proficiency Testing Providers

A2LA recommends that, whenever possible, A2LA-accredited testing and calibration laboratories use accredited PT Providers to meet the A2LA requirements for participation in proficiency testing. However, we recognize that accredited PT Providers may not be available for all technical disciplines, or that specific accreditation programs may mandate participation in other comparisons. Therefore, if there are no accredited alternatives available and if the samples offered by the non-accredited programs are relevant to the work your laboratory performs, we recommend that you contact them to discuss enrollment options. A2LA document I106 - Available Proficiency Testing Programs provides a non-comprehensive list of proficiency testing programs of which A2LA is aware.

  • C1 - Available for Commercial Services
  • C2 - Conditionally Available for Commercial Services
  • C3 - Not Normally Available for Commercial Services
