| Abstract: | The application of content validity to a merit examining process or rating schedule requires an extension of the concept beyond that of work samples and tests of knowledges or skills to measures of ability and personal characteristics. A method for accomplishing this without violating the principles of content validity is presented. This technique, called the job sampling approach, is a task-based, structured system of eliciting the information necessary to construct the rating schedule from sources most able to provide that information and for using the information to construct the rating schedule and linking it to job performance. The steps include: definition of the performance domain of the job in terms of process statements; identification of the selection and measurement objectives of the organization; development of the measurement domain in relation to the performance domain and to the selection and measurement objectives; and demonstration that a close match between the performance domain and the measurement domain was in fact achieved. |
