This study compared levels of achievement of three groups of Houston (Texas) police academy cadets: those with no military service but with 60 or more college credit hours, those with military service and 0 hours of college credit, and those with military service and 1 to 59 hours of college credit. Prior to 1991, police cadets in Houston were required to have a minimum of 60 hours of college credit; however, following the Gulf War, an ordinance exempted military personnel from the 60-hour requirement. The study design was a one-way analysis of variance, with a five-year stratified sample of n=273 participants. Achievement levels were determined by scores on a reading comprehension test, a state licensing test, and a Civil Service examination, as well as by academic average, driving skills, and firearms performance. The study found that cadets without military service but with 60 or more credit hours scored higher on reading comprehension and state licensing and civil service examinations than the other two groups. Driving skill scores were not affected by either college hours or military service. Cadets with military experience performed better at firearms skills than those without military experience. Appendices include data tables, permission letters, and law enforcement statistical data. (Contains 76 references.) (RH)
