The present study investigated the construct validity of an occupational classification system based upon ability requirements. This was done by placing the positions held by a large, nationally representative sample of full-time, employed, young, civilian adults into the classification system (the Occupational Aptitude Patterns Map) and determining whether the patterns of characteristics exhibited by the groups of positions coincided with the patterns predicted by relevant theories on job ability requirements and job differentiation. The results largely supported the validity of the Occupational Aptitude Patterns Maps as an occupational classification system. The results indicated that the Map captures differences across positions in their requirements for cognitive ability, although the overlap across job clusters is enormous. The Map also differentiates jobs on the basis of their requirements for specific abilities (e.g., scientific/mechanical ability). The differences across clusters in cognitive ability shares overlap with differences in occupational prestige as well as differences in rated job characteristics. The extent of this overlap was smaller than expected. Ideas for future research and methodological caveats are discussed.
