Presented is the development of a repository of work-related personality items that may be used to assess job-related traits identified by the Personality-Related Position Requirements Form (PPRF: Raymark, Schmit, & Guion, 1997). Analyses of the item pool administered to a sample (n = 412) of trade apprentices showed evidence to support the12 work-related Big 5 sub-dimensions identified by the PPRF. A smaller validity study (n = 47) suggested that personality dimensions identified as job-related by the PPRF were related to important job-related outcomes
