Dictionary of Occupational Titles, Fourth Edition, Volume 1. Revised 1991

摘要

The Dictionary of Occupational Titles (DOT) was developed in response to the demand of an expanding public employment service for standardized occupational information to support job placement activities. In order to properly match jobs and workers, the public employment service system requires that a uniform occupational language be used in all of its local job service offices. Highly trained occupational analysts must go out and collect reliable data which is provided to job interviewers so they may systematically compare and match the specifications of employer job openings with the qualifications of applicants who are seeking jobs through its facilities. In order to look at the millions of jobs in the U.S. economy in an organized way, the DOT groups jobs into 'occupations' based on their similarities and defines the structure and content of all listed occupations. Occupational definitions are the result of comprehensive studies of how similar jobs are performed in establishments across the nation and are composites of data collected from diverse sources. The term 'occupation', as used in the DOT, refers to this collective description of a number of individual jobs performed, with minor variations, in many establishments.
