The Portland (Oregon) Plan for Drug-Free Schools was so well-accepted in its first year that it was expanded from six middle schools in 1987-88 to all middle schools in the Portland Public Schools in 1988-89. The program was originally implemented in grades 6-12, with a special focus on six middle schools. The goals are the following: (1) develop a comprehensive drug and alcohol prevention counseling program and materials; and (2) promote cooperative prevention partnerships among administration, staff, parents, public/private agencies, and community leaders. The two components of the plan consist of direct services to six middle schools, and district-wide technical assistance to improve the quality of services and support groups. Services are targeted to students who are themselves substance abusers or who are children of alcoholics or drug-affected families, and to at-risk students. Evaluation methods included a Stages of Concern questionnaire for facilitators, observation of support groups, and interviews with project staff and school administrators. The findings of the evaluation include suggestions for improving some areas of the program. Statistical data are included on twelve tables and three graphs. A brief bibliography is also included. The appendices include the following: (1) Risk Factors for Substance Abuse; (2) Stages of Concern Questionnaire; (3) School Counselor Alcohol/Drug Interview Questionnaire Summary Responses; (4) Parent Contact Log and Agency Contact Log; and (5) Alcohol/Drug Discipline Policies.
