AAFCO’s Proficiency Testing Program (PTP) is accredited to ISO/IEC 17043:2010 by ANAB. The Proficiency Testing Program (PTP) Committee supports regulatory, industry and commercial feed laboratories by providing a proficiency testing program that is compliant with international guidelines at nominal cost to laboratories.
Proficiency Testing rounds are distributed to customers on a predetermined schedule and are tested for analytes of interest by each laboratory. Results for individual analytes are reported using specified AAFCO method codes and units to allow for statistical analysis of the performance of individual methods or method types. Laboratory results are reported using our Data Reporting Website. Reported results are analyzed statistically and customers are provided with performance scores for each analyte and method reported.

Please note that due to recent shipping restrictions in the U.S., AAFCO can no longer provide proficiency testing services to Russia and Venezuela.
