The psychological screening of police candidates is a hotly debated topic. The type of measures used lacks consistency and standardization. This often can lead to a candidate "shopping" for a psychologist who will eventually agree to his or her mental fitness for policing. More recently, the field of police psychology has received attention as a viable field of psychology, part of which involves the assessing of candidates for police employment. A possible hypothesis is that there would be consistency among police psychologists, who would differ from clinical psychologists, as to what measures should be used and why for assessing such candidates. Recent research suggests there is no consistency or differences.
