This volume is a "translation" of the Dictionary of Occupational Titles (DOT) and its Supplements into the Holland classification system. The Holland classification uses six main categories--Realistic, Investigative, Artistic, Social, Enterprising, and Conventional--to characterize occupations. These main groups are used to form 3-letter subgroups that are useful in assessing the degree of congruence between a person's interests or preferences and any of thousands of occupations.

• Makes the 12,860 occupational titles frm the DOT and its supplements more accessible to counselors, clients, and researchers who use the Holland classification to find or organize occupational information.
• Provides cross-reference indexes between DOT and Holland codes.
• Codes reflect current job analysis information, recent changes in work environments, and industry trends.
• Provides valuable information about the distinguishing characteristics of each occupational class, the distribution of occupations among the categories, Holland codes for U.S. census and Standard Occupational Classification systems, as well as the validity of the classifications.
• Links Holland occupational codes to seven of the most widely used occupational classifications and information sources in the U.S.:
  Dictionary of Occupational Titles and its Supplements.
  The Occupational Employment Statistics System.
  The Standard Occupational Classification Manual.
  The Census Occupational Classification.
  The Classification of Instructional Programs.
