Proficiency Testing Australia

How confident are you of your testing and measurement results?


Proficiency testing is a means of assessing the ability of laboratories to competently perform specific tests and measurements.

Proficiency Testing Australia (PTA) is a subsidiary of the National Association of Testing Authorities, Australia.

Programs PTA offers


PTA offers Testing Programs involving the distribution of sub-samples of a material for testing by participating laboratories, Measurement Programs involving the circulation of a measurement artefact among a group of laboratories or a single laboratory, and customised programs, for industry organisations.

For Testing Programs, a laboratory’s performance is normally a comparison to consensus values calculated from the results submitted.

For Calibration Programs, laboratory results are compared to values established by a reference laboratory, taking into account measurement uncertainties.


All information supplied by a laboratory as part of a proficiency testing program is treated as confidential.

Training and consultancy

PTA provides training courses and consultancy services on proficiency testing and statistical applications.
