Psychological aptitude testing is part of the core body of applied psychology and has a long-standing tradition. In the context of security-related issues, it is even of crucial importance, as the prevention of human-caused damage is a very high priority. However, in order to make reliable and sustainable statements using psychological aptitude testing, it is advisable to combine the psychological component with perspectives from risk management. The presentation will first introduce a practice-oriented repertoire of human risks developed at the IAP Institute for Applied Psychology at ZHAW, and second present an approach in which risk-oriented aptitude diagnostics in a professional context (not clinical and not forensic) translates the findings of aptitude diagnostics into the language of risk management, thus making them accessible for risk-oriented decisions. The seven risk areas presented are lack of competence, self-harm, human error, lax work attitude, rule violations, intentional rule breaking, and destructive leadership behavior. The approach of risk-oriented aptitude diagnostics in a professional context is based on four steps (after a requirements analysis has been carried out and the assessment process has been developed): Recognition of conspicuous features - Identification of relevant risks - Assessment of risks - Risk communication.
