Proficiency Testing is the use of inter-laboratory test comparisons to determine the performance of individual laboratories for specific tests.
why is it important for sensory labs?
Proficiency Testing is used to monitor the consistency and comparability of a laboratory's test data with other similar laboratories. This is an important prerequisite for studies in which more than one lab is involved.
what does esn do concerning proficiency testing?
The ESN provides regular Proficiency Testing schemes for sensory ranking and descriptive profiling. These projects are financed by a participation fee. Costs are dependent on the type of proficiency test, and the number of participants (usually between 2000-3000 Euro). There are clear benefits:
- Participation helps to demonstrate the reliability of sensory panel results, which is beneficial towards accreditation (e.g. through UKAS & ISO).
- Participants are shown their performance for each of the performance criteria to help pinpoint where improvement or further training is needed.
- Participation can foster confidence in the results of a sensory panel, for management and clients.
- Proficiency Testing helps to encourage improvement.
