Intended for use with or without counseling help, this occupational exploration guide is organized around 12 interest areas, 66 work groups, and 348 subgroups of occupational titles. The interest areas (an expansion of John Holland's six occupational categories) represent the broad interest requirements of occupations as well as the vocational interests of individuals. Within each interest area are work groups (occupational clusters) suitable for exploration by those who have a particular interest. Each work group section contains descriptive information and listings of jobs by "Dictionary of Occupational Titles" (DOT) name and code. Information on each work group is presented under the following question headings: What kind of work would you do? What skills and abilities do you need? How do you know if you would like or could learn to do this kind of work? How can you prepare for and enter it? What else should you consider about these jobs? Appended is an alphabetical listing of all DOT titles and codes listed in the guide. Other appendixes explain how the twelve interest areas were developed, describe the U.S. Employment Service (USES) Interest Inventory (under development) and its General Aptitude Test Battery (GATB), list occupations for which Specific Aptitude Tests (SATBs) have been developed, and suggest uses of the guide for cataloging and filing occupational information materials.
