WELCOME to American Proficiency Institute

At American Proficiency Institute, we bring you the best in proficiency testing by providing technical excellence and creating innovative solutions that help you manage your proficiency testing.

Every aspect of your proficiency testing is controlled by you -- how you choose to receive your test kits, how you report results, and whether to review test results using traditional reports or using graphical analysis. Throughout the entire process, you have the backing of the most advanced proficiency testing organization in the world.

We are now accredited by A2LA to the international PT quality standard, ISO/IEC 17043:2010. Click the A2LA Accredited symbol above to access our scope of accreditation.
