High school academies are three-year schools-within-schools offering economically disadvantaged students an integrated academic-vocational education, career development and enrichment activities, and nonacademic supports and employment opportunities. The academies represent a many-faceted approach to linking business and industry with schools, involving a successful combination of school-based changes and outside interventions that is sustained over time. Evaluation of programs in Philadelphia (Pennsylvania), California, Portland (Oregon), and Pittsburgh (Pennsylvania) found that the chief considerations for program success are site selection, industry focus, and lead time for program development. The experience of newer academies indicates that attention to the following features during replication is also critical: (1) strict adherence to the academy model; (2) a defined student selection process; (3) an integrated academic-technical program; (4) strong private sector support; (5) a strong career planning component; (6) a full range of student support services; (7) a high degree of commitment from the school district; and (8) identifiable space dedicated solely to the academy. Technical assistance in organization, curriculum development, private sector involvement, and public relations is strongly recommended. The following materials are appended: (1) a 16-item bibliography; (2) a list of essential replication tasks; (3) a directory of academy contact people; and (4) a list of the academies. (FMW)
