Development of a Job Analysis‐based Procedure for Weighting and Combining Content Related Tests Into a Single Test Battery Score

By definition, content‐related approaches to test validation do not rely on criterion data. As a consequence, regression and other statistical procedures for weighting and generating a composite score from a test battery are not applicable when a content‐related validation strategy is used. This paper presents a procedure for determining the component weights for a test battery that has been developed on the basis of a content‐related validity strategy. The Relative Content Contribution (RCC) weighting procedure is a logical extension of the conceptual basis underlying the rational developmental process used to demonstrate the validity of content‐related tests. Results from field implementations of the procedure in the development of two promotional test batteries (fire and police) and an entry‐level test battery (police) in two large metropolitan cities are presented to illustrate the procedure.
