Individual Psychological Assessment: A Core Competency for Industrial–Organizational Psychology

Individual Psychological Assessment is widely practiced among I–O psychologists and supported as a core competency by a majority of the commentaries. Our response addresses some of the key points made in the commentaries, such as issues related to the definition, contextual and criterion variables, interpretation and integration methods, validity evidence, professional matters, and future research directions. We also respond to a few critics who want to entirely eliminate expert assessor judgment in IPAs. Models are presented for using assessor judgment and mechanical methods in IPAs and for distinguishing naïve and sophisticated IPA researchers and practitioners. We conclude that IPA is now widely accepted as a core part of I–O psychology.
