EPTIS - The European Proficiency Testing Information System
This Link applies to: Any version.
The EPTIS database lists hundreds of PT schemes (PTS) operated in Europe and the Americas. It aims at helping you to find a suitable PTS in this quite intransparent market. The focus is on the field of testing; metrological and clinical PTS are not included systematically. EPTIS is a non-commercial, joint publication of many international organisations in Europe and the Americas, and open for further international participation.
