The Personality-Related Position Requirements Form (PPRF), a job analysis form to be used in making hypotheses about personality predictors of job performance, is described. The Big Five personality factors provided an organizing framework for the PPRF. Subsequent development resulted in identifying 12 specific sets of items for facets of each of the Big Five. A study was conducted by gathering job descriptions on 260 different jobs to determine if the PPRF could reliably differentiate jobs; such evidence was found. The PPRF is offered to both researchers and practitioners for use, refinement, and further testing of its technical merits and intended purposes.
