Welcome to Proficiency Testing Canada (PTC)
Since 1991, Proficiency Testing Canada (previously operating under the Canadian Association for Laboratory Accreditation – CALA) has been providing proficiency testing for laboratories to help monitor performance and compare results amongst peers.
As of January 1st, 2020, PTC will operate as a separate and distinct corporate entity responsible for all proficiency testing activities previously held by CALA. PTC will continue to honour CALA member discounts on proficiency testing. Our scope of accreditation can be found online here.
We are in the process of building our new website at ptcanada.org. During this period, you can continue to find all proficiency testing documentation on the CALA site, including web data entry.
We apologize for the inconvenience. If you have any questions, please feel free to direct them to email@example.com.
