The goal of the Phoenix Pilot Drug Program is to provide a drug/alcohol free educational environment which will enable students to reduce their drug/alcohol usage and function in a regular school program. To determine the degree to which the program is accomplishing these short-term goals, and also to examine the adequacy of the counseling program, the academic environment, and the relationship between parents and school, process evaluation data were collected through observation of counseling sessions and classes; review of course materials, objectives, and school records; and interviews with students and staff, and the principal. A matched comparison student was selected for each Phoenix school student in the sample, to confound uncontrolled sources of variation; 10 Phoenix school students were included in the study. The findings, summarized in terms of program goals and objectives, showed that the program is effective in providing a drug free environment for students while they are in school. However, students' self-reports indicated that the program had no effect in reducing overall drug and alcohol use. The program did appear to be strengthening students' commitment to school and the rebuilding of good school habits. The counseling program was not found effective in decreasing drug use or in improving students' self-esteem. An individualized academic environment was found lacking, but learning habits had improved. While the partnership between school and home requires further investigation, indications are that more parent involvement is needed. (JAC)
