The Marin County program emphasizes services to juvenile probationers through the school system. Five probation officers were placed in school buildings, and carry out their duties informally by meeting students in corridors, lunchrooms, and school yards. They stress their functions as officers of the court enforcing probation requirements and counseling roles; probation officers do not become involved in school security or law enforcement matters. The program in Sacramento County focuses on curtailing dependency in drug users. The probationers are tested twice weekly for substance use, are referred to human services agencies for assistance, and are monitored closely in the field. Minimum program participation is 6 months. The Orange County program uses a community-centered approach emphasizing surveillance and treatment. The program emphasizes heavy contact with probationers in the offices and in the probationer's home as well as contact with families. Most of the clients did well at first, but began to drop out after 3 years of work. The program has become more surveillance oriented over time. Photographs are provided.
