Suitability for hire and fitness for duty evaluations (FFDEs) for police officers are complex evaluations that attempt to predict one’s suitability for being hired as a police officer or to determine fitness to continue to serve as an officer. There are multiple issues with regard to conducting these assessments; some of the issues addressed in this entry are (a) predictive validity; (b) normative samples, defensiveness, and response styles; (c) the California Peace Officer Standards and Training (POST) dimensions; (d) typical problems with police officers; and (e) typical types of psychological measures that are used in conjunction with police evaluations.
