A comparative evaluation of two approaches to job-knowledge test construction

Abstract

204 airplane and engine mechanics were given a battery comprising three requirements-centered tests (based on job knowledges implied in training courses and handbooks) and three experience-centered tests (based on one or more topics representing distinctive learning opportunities afforded by a job). Peer ratings and length of experience were used as criteria. "Experience-centered tests discriminate unambiguously in favor of high-experience mechanics generally approved by their peers. Requirements-centered tests… [only] tend to isolate sub-groups rated Poor, but do not distinguish knowledge presumably learned primarily through experience."
