A cooperative effort between the Rockville Centre Free Union School District and the Far West Laboratory evaluated the implementation and outcomes of Greenhouse, an alternative high school program using the experience based career education (EBCE) curriculum. Evaluation criteria included four process objectives and the following student learning objectives: (1) improving reading, writing, quantitative, oral communication and interpersonal skills; (2) improving attitudes toward career planning, learning and education; (3) increasing career-related self awareness; (4) increasing career planning involvement; (5) acquiring career-related information; (6) increasing career decision making ability; and (7) increasing self-reliance. Pretest and posttest data were gathered from an experimental group, comparison group, and self-selected group of students. In addition, information in student files, administrative records, and opinion surveys sent to parents and resource persons were used in evaluating the program. Findings indicated that twenty-two out of twenty-five seniors enrolled in Greenhouse graduated and that some preset criteria were achieved for all but one of the student learning objectives. In addition, both parent and students were found to be strong supporters of the program.
