The purpose of this practicum was to test the effectiveness of a security training program at Trenton Central High School. A professional, trained security force was necessary to reduce school crime. A training program lasting eight and one-half months was instituted. A pilot study at the end of the training program was conducted comparing the attitudes of security officers, students, and staff at Trenton Central and another secondary school in the district. The results showed that the training program improved relationships among students, staff, and officers and created a professional force. The trained security officers contributed to the reduction in school crime and civil suits against the school. (Author/DW)
