AATCC offers several Proficiency Testing Programs. These programs allow companies to determine how their laboratories perform in comparison with others around the globe. Samples are sent from the AATCC Technical Center to participating laboratories along with instructions and report forms. Those laboratories are asked to perform the required tests on the fabric samples provided by AATCC and return their completed report forms to AATCC. AATCC then compiles the data and sends a summary report to the participating laboratories. Each laboratory is assigned an anonymous lab code, and only those laboratories that participated receive the summary report.
