Selecting the right proficiency testing scheme for my laboratory


EURACHEM through its Proficiency Testing Working Group has produced an information leaflet to help laboratories select the most appropriate proficiency testing schemes. Several PT schemes are often available for the same area of testing, so this leaflet focuses on key questions that can help laboratories choose those PT schemes that are best suited for their needs.

This second edition updates the leaflet to reference current guidance on PT.


The second edition is currently available in the following languages. Links to translations of the first edition, available in 14 languages, are temporarily maintained on this page (below) for convenience while translations of the second edition are prepared.


Please consult the PT Working Group Chair if you would like to prepare a translation in your own language.
