The primary purpose of this study is to highlight similarities and differences among 17 computer-assisted career guidance (CACG) systems so that practitioners, CACG system developers, policy makers, and researchers may make informed decisions concerning such systems. The CACG systems in the analysis are: (1) Career Information System; (2) Career Visions; (3) Choices: (4) Choices CT; (5) Choices Jr; (6) MODULAR C-LECT; (7) C-Lect Jr.; (8) COIN; (9) COIN Jr; (10) DISCOVER for Colleges and Adults; (11) DISCOVER for High Schools: (12) DISCOVER for Junior High and Middle Schools; (13) Guidance Information System Version 17; (14) GIS II; (15) SIGI PLUS; (16) VISIONS; and (17) VISIONS PLUS. The analysis looks at features including system content, user friendliness, and support materials and services available from the developer. It also looks at costs, such as system-specific costs, and constant costs that exist irrespective of the specific system used. A secondary purpose of the study is to provide a comprehensive description of the 17 systems included in this analysis by identifying state, territory, and city-specific availability of occupational information in the CACG systems and by identifying the country location, geographic data base origin, and language for each system. Eleven tables are included. Contains four pages of references. (Author/JE)
