​​​​​​​​​I​ntroduction

Proficiency Testing (PT) scheme participation allows laboratories to:

  • objectively monitor and improve the quality of their measurement results in terms of accuracy and comparability,
  • independently demonstrate the continued competency of their analytical staff, and
  • demonstrate the effective maintenance of quality assurance systems.

Regular PT scheme participation is also a prerequisite to obtain and maintain ISO\IEC 17025:2017 accreditation for the competency of testing and calibration laboratories.​
