Wais-III norms for working-age adults: a benchmark for conducting vocational, career, and employment-related evaluations

The Wechsler Intelligence Scales are routinely used to assess threshold variables which correlate with subsequent job performance. Intellectual testing within educational and clinical settings accommodates natural developmental changes by referencing results to restricted age-band norms. However, accuracy in vocational and career consultation, as well as equity in hiring and promotion requires the application of a single normative benchmark unbiased by chronological age. Such unitary norms for working-age adults (18- to 64-yr.-olds) were derived from the WAIS-III standardization sample in accord with the proportional representation of the seven age-bands subsumed within this age range. Tabular summaries of results are given for the conversion of raw scores to scaled scores for the working-age population which can be used to derive IQ values and Index Scores.
