This practicum developed a program to enhance the job performance of support personnel (behavior modification technicians) who work with students having conduct disorders. The behavior modification technicians provided building-level support for principals and teachers working with black adolescents from socially deprived backgrounds. Inservice activities were designed and implemented over a 16-week period in the following areas: human growth and development, preadolescent and adolescent development, behavior disorders, pharmacological intervention, behavior analysis, developing anecdotal records, developing Individualized Education Plans, interagency networking, conflict resolution, and program and school guidelines. Participants also were required to design and implement behavioral objectives and show mastery of aggressive control techniques (therapeutic holds) and parent involvement skills. During an additional 16 weeks, participants met and discussed individual student problems. Participants received the training at no cost, and received 3 semester hours credit from the local state university. Significant gains were found in acquired knowledge after participants completed the inservice activities. Support personnel displayed significant gains not only in technical support skills, but also in self-esteem. Appended is a post-training test. (Contains 36 references.) (DB)
