Proficiency Testing Provider Accreditation Program

The A2LA Proficiency Testing Provider Accreditation Program is designed for proficiency testing providers seeking to be recognized for operating a management system and demonstrating technical competence in all aspects of proficiency testing schemes.

Our team of industry experts assess the technical capabilities of the provider to determine competency in production, testing and statistical approaches to handling homogeneity and stability of the test sample/artifacts and the analysis of participants data. This value-added assessment results in a globally recognized accreditation.

A2LA is recognized by The NELAC Institute (TNI) to provide accreditation to the rigorous TNI Requirements for Stationary Source Audit Sample Providers and TNI Proficiency Testing Providers.

For the TNI Proficiency Testing Providers, in addition to providing a biennial on-site assessment to ensure technical competency in production, statistical approaches and reporting, we maintain a database whereby we are monitoring PT studies on an ongoing basis between on-site assessments.
