Any analyst enrolled in the AAR program must successfully participate in the AAT program.

A proficiency testing program provides objective evidence of an analyst's capability to produce data that is both accurate and repeatable. Participation in proficiency testing activities also provides invaluable feedback in the internal monitoring of your quality system and can help analyze the reliability of an organization's analytical protocols, personnel, and equipment.

Proficient performance is a requirement for recognition as an AAR Registered Analyst and inclusion on the AAR Directory of Registered Organizations and Analysts.

The AAT Program is the proficiency testing program for fiber-counting analysts who seek to be included on the Asbestos Analysts Registry. Only analysts enrolled in the AAR may participate in the AAT program. Participating organizations may have analysts that work in the laboratory or the field or both.

When an organization enrolls in the AAR Program their affiliated analysts are enrolled in the AAT program. Analysts may also be enrolled with an organization after the initial application submission.

Samples are shipped quarterly to the organization's AAT Contact. One sample set can be analyzed by up to five analysts. Sample analysis must be performed using the current version of the NIOSH 7400 Method. Analytical procedures must be in compliance with the OSHA asbestos standard, 29 CFR 1910.1001. AAT data must be submitted to the AAT Data Dashboard by the deadline.

AAT Performance Results Reports are available within 10 business days after the round closes. The reports display the proficiency results and status of each enrolled analyst.
