Results from seventy two laboratories participating in GeoPT3, round three of the international proficiency testing programme for analytical geochemistry laboratories, are presented. The report includes analytical results contributed by participating laboratories, together with the z‐scores derived from these results using appropriate fitness for purpose criteria. These data are available for use as part of the laboratories’ quality control procedures to assess the reliability of analysed results.
