This study examined similarities and differences among 15 computer-assisted career guidance (CACG) systems: (1) the Career Information System; (2) Choices; (3) Choices CT; (4) Choices Jr; (5) MODULAR C-LECT; (6) COIN; (7) COIN Jr; (8) DISCOVER for Colleges and Adults; (9) DISCOVER for High Schools; (10) DISCOVER for Junior High and Middle Schools; (11) Guidance Information System Version 17; (12) Guidance Information System; (13) Kansas Careers; (14) SIGI PLUS; and (15) VISIONS. The feature-cost analysis included features of system content, user friendliness, and support materials and services available from the developer; and costs of system-specific costs and constant costs. Data were gathered from CACG software use, support materials provided by developers, and telephone interviews with developers. Results are provided in tables. Tables 1 through 4 provide data on 12 CACG systems used in high school, college, employment service, vocational-technical school, library, rehabilitation correctional, and military settings. Table 1 includes system content, table 2 includes user friendliness, table 3 includes support materials and services available from the developer, and table 4 includes costs. Tables 5 through 8 provide a similar sequence of data on three CACG systems used in junior high/middle schools. Table 9 identifies state, territory, and city-specific availability of occupational information in the CACG systems. Table 10 identifies the country location, geographic data base origin, and language for the CACG systems. Table 11 provides addresses and telephone numbers of the 15 CACG system developers.
