    AASHTO Accredited laboratories undergo vigorous on-site, third party assessments. During these assessments, each test method is demonstrated in its entirety by the laboratory’s technical staff, and the testing apparatus associated with each test is evaluated. The assessment also includes a thorough review of the laboratory’s quality management system, including records of technician training and competency evaluations as well as equipment calibration and check records. Additionally, a detailed review of all accreditation requirements, including participation in the AASHTO re:source and CCRL proficiency sample programs, is conducted for each accredited laboratory at least once per year.
