The Comprehensive Approach to Substance Abuse Prevention Training Program (Project CAST) was a federally funded pilot project designed to establish, expand, and enhance staff development for educational personnel in substance abuse prevention education. This was to be accomplished by establishing a training program for both instructional and non-instructional staff, as well as developing a guide for integrating prevention techniques and strategies into the everyday responsibilities of staff. Trainees (N=134) included teachers, social workers, paraprofessionals, secretaries, principals, and assistant principals, all of whom took part in a series of training workshops conducted by a team of specialists from Bank Street College. Feedback from participants indicated that the workshops were very useful, and pre- and post-test results showed a marked increase in knowledge. The following two changes were recommended for future implementation of Project CAST. First, a more active recruitment of training participants, particularly non-instructional staff is needed to enlist the targeted number of participants. Second, a greater collaboration between the project director and the curriculum development team is needed during the curriculum design process. This can help to ensure that the end product meets the goals of the project--to develop a staff training curriculum for both instructional and non-instructional staff. (ABL)
