Job Analysis: Job Classification Systems


The Occupational Information Network, encompases changes to the DOT in terms that reflect the latest research in the field of job analysis. By identifying and describing the key components of modern occupations, O*NET supplies up-dated information critical to the effective training, education, counseling and employment of workers. O*NET contains data describing over 1,100 occupations. O*NET also contains linkages that crosswalk O*NET occupational titles to eight other classification systems (DOT, MOS, OPM, etc.). O*NET uses "Occupational Profiles" to give a short overview of the most important data descriptions on each occupation.

Dictionary of Occupational Titles (DOT)

The Dictionary of Occupational Titles (DOT) was created under the sponsorship by the Employment and Training Administration (ETA), and was last updated in 1991. The DOT was replaced by the O*Net, and ETA no longer supports the DOT.
The O*Net is now the primary source of occupational information. It is sponsored by ETA through a grant to the North Carolina Department of Commerce. Thus, if you are looking for current occupational information you should use the O*Net.
The Dictionary of Occupational Titles (DOT) was developed in response to the demand for standardized occupational information to support an expanding public employment service. The U.S. Employment Service established a Federal-State employment service system, and initiated an occupational research program, utilizing analysts located in numerous field offices throughout the country, to collect the information required. The use of this information has expanded from job matching applications to various uses for employment counseling, occupational and career guidance, and labor market information services.

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. Occupational analysts collect data provided to job interviewers to systematically compare and match the specifications of employer job openings with the qualifications of applicants who are seeking jobs through its facilities.

Australian and New Zealand Standard Classification of Occupations

The Australian and New Zealand Standard Classification of Occupations (ANZSCO) is a skill-based classification of occupations which used as the Australian national standard for producing and analyzing labor force statistics, human resource management, and the listing of job applicants and vacancies.
This system classifies jobs according to skill level (e.g., the amount of formal education, on-the-job training and previous experience necessary to perform the job) and skill specification (e.g., the knowledge required, the tools and equipment used, the materials worked on and the goods and services produced).

U.S. Standard Occupational Classification System

The Occupational Classification System manual was created for Bureau of Labor Statistics (BLS) field economists to help ensure correct occupational matches when collecting compensation data. Available to the public, this manual allows the user to lookup job descriptions for occupations found in the NCS bulletins and is used by field economists in the classification of thousands of occupations.
