This paper summarizes the contents, structure and possible uses of the Information System for Vocational Decisions (ISVD) data file on military jobs in the 3 major services. In all, 170 specific career fields for enlisted men and 34 for officers are included in the data file, which also provides for converting the inquirer's personal characteristics and preferences to a list of possibly suitable jobs within the military. In the appendices are included samples of the scripts used with the military datafile and a fairly extensive bibliography of materials which can be used in conjunction with the ISVD computer-assisted instruction program.
