Popis:	Assigned values derived from the GeoPT proficiency testing programme were compared with certified values for six certified reference materials that have been used as test materials in the GeoPT programme. Statistical analysis showed that there were few significant differences between these sets of data and that these differences had no significant impact on the GeoPT assessment when fitness-for-purpose criteria were taken into account. Les valeurs attribuees derivees du programme de test d'aptitude GeoPT ont ete compares avec les valeurs certifiees pour six materiaux de reference certifies qui ont ete utilises comme materiaux de test dans le programme GeoPT. L'analyse statistique a montre qu'il y avait peu de differences significatives entre ces ensembles de donnees, et que ces differences n'ont eu aucune incidence significative sur l'appreciation GeoPT quand les criteres d'usage ont ete pris en compte.
