PT Provider Accreditors

The Proficiency Testing Provider Accreditor (PTPA) establishes and implements a program to accredit PT Providers and to monitor accredited PT providers to ensure that their studies and practices meet all applicable standards. The PTPA shall meet the requirements established by TNI. An organization may apply to be recognized as a PTPA to the TNI PT Program Executive Committee (PTPEC). The PTPEC will determine whether the organization meets the requirements. Currently, TNI recognizes two organizations as PTPAs:

ANSI-ASQ National Accreditation Board / ACLASS

American Association for Laboratory Accreditation / A2LA
