PT Schemes

Cawood’s divisions participate in a range of PT (Proficiency Testing) Schemes which assess the quality of testing between different laboratories. Each participating laboratory is given sample tests for analysis, with the results reported to the scheme organisers. PT schemes are important to give an insight into our performance, benchmarking against other laboratories, as well as to demonstrate to our customers our commitment to quality. Cawood is also involved in organising PT Schemes for some sectors.
