Results of this study indicate that, with both populations, Police and Security Applicants, the LEAl was able to screen those candidates who were more likely to be successful long term in their careers in law enforcement. Further implications discussed include the growing number of specialised treatment populations, such as the mentally ill and sex offenders. Because these populations require a higher level of care and more hands on involvement than is traditionally required of officers, screening in officers who are more appropriately fit to work with such populations is extremely important and necessary.
