An evaluation of the effectiveness of the School Team Approach for changing perceptions of the school climate and the level of victimization in 290 middle, junior high, and high schools used student and teacher questionnaires adapted from those used in the Safe School Study. In pre-intervention tests, students and teachers in middle and junior high schools generally reported higher levels of problems than did their counterparts in high schools. In middle and junior high schools the students' perceptions of danger were related to student-teacher alienation. However, among high school students and among teachers at all secondary levels, perceptions of danger were related to the character of the neighborhood in which their schools were located. Evaluation of the interventions indicated that the objectives of the team program were more important in determining outcomes than were the strategies used. It was also found that changes in student behavior could be obtained either by working directly with students or with the adults around them. Finally, the evaluation results indicated that different situations must be met with different intervention techniques. (Author/PGD)
