Abstract
This paper describes issues in developing a scientifically based system for relating the abilities of people required to perform jobs to the nature of the task characteristics of these jobs. Conceptual and methodological issues in classifying tasks are discussed as are the objectives of task taxonomies and criteria for their evaluation. Alternative taxonomic approaches are described. A particular approach to classifying tasks in terms of ability requirements is described in more detail and evaluated according to a number of criteria and applications. These latter include encouraging utility in job analysis, test development, setting performance standards, and classifying jobs into families.
