Proficiency Testing Schemes (Round Robin) are services aimed at evaluating the performance of calibration and testing laboratories through interlaboratory comparisons. The laboratory participation in a proficiency test is one of the most efficient ways to evaluate its technical competence, as it allows comparison in the same field, establishing a benchmarking. In a broad context, a proficiency test enables the participating laboratory to:

  • Continuous assessment and your performace monitoring;
  • Evidence or confirmation of achievement of reliable results;
  • Identification of problems/errors related to the performed tests/analyzes;
  • Taking corrective and preventive actions and evaluation of internal controls that the laboratory has;
  • Determination of performance characteristics, validation of methods;
  • Standardization / adequacy of methodologies to the market and recognition of results nationally and internationally;

Proficiency tests and interlaboratory comparisons are key to credibility enhancement of measurement results and, consequently, they contribute to the improvement of international trade and the prevention of technical barriers. ITAK´s proficiency tests are globally accepted, with the current participation of companies from over 30 countries.
