Physical Job Demands in Police Officer Selection and Training: Normative Data and Predictive Validity-A Research Note

For police officers, a high level of physical fitness is a prerequisite to meet both the training demands during education and the job demands of police service successfully. Before police officers enter the service, they have to pass a selection procedure and to complete a course of study or training. The present study has two aims. First, we describe the physical fitness of police applicants based on basic physical abilities in the context of the personnel selection procedure (research question 1, normative data). Second, we investigate the relationship of police applicants' physical fitness based on basic physical abilities in the context of personnel selection and subsequent levels of physical performance on a complex physical task in police training (research question 2, predictive validity). Based on two samples of N = 2082 police applicants and N = 424 police trainees in education, two main findings emerge. First, we provide normative data on the physical ability levels of police officer applicants derived from personnel selection procedure. Second, we report empirical evidence on the relationship between basic physical ability levels in the selection procedure and subsequent physical performance levels in a complex physical task during police training. Based on our data, performance-based thresholds for personnel selection procedures can be defined to minimize the risks of injury or failure associated with personnel selection and police training. Finally, evidence-based recommendations for police training, implications for further research, and limitations are discussed.
