Key findings are presented from a survey conducted by the California Research Bureau showing that most California school districts incorporate violence prevention program curricula with a strong police and security presence. Many schools have installed closed circuit video surveillance cameras, canine searches, and metal detectors. Unfortunately, the vast majority of schools who actively use violence prevention and anti-drug use curricula are unable to directly measure the impact or effectiveness of these programs on reducing violence and drug use among students. Many small schools rely on school staff, teachers, and volunteers to provide supervision and security during school hours. Few California schools have brought together the key elements of students, parents, and civic and public officials to formulate a community response to school violence. While there are nearly 13,000 part-time and full-time school district personnel providing security in California K-12 schools, few are trained or certified in these types of jobs. By contrast, the state's largest school districts have their own police forces. Only 10 percent of medium-sized districts and fewer smaller districts have a dedicated school police force. A substantial number of school districts have agreements and contracts with municipal police or local law enforcement agencies. An appendix provides the survey questionnaire. (GR)
