The 2010 Standard Occupational Classification (SOC) system is used by Federal statistical agencies to classify workers into occupational categories for the purpose of collecting, calculating, or disseminating data. All workers are classified into one of 840 detailed occupations according to their occupational definition. To facilitate classification, detailed occupations are combined to form 461 broad occupations, 97 minor groups, and 23 major groups. Detailed occupations in the SOC with similar job duties, and in some cases skills, education, and/or training, are grouped together. General questions concerning the SOC may be sent by email or faxed to 202-691-6444.
Updated timeline for the 2018 SOC
Revising the SOC is a multi-year process, during which the SOC Policy Committee (SOCPC) formulates recommendations for revisions that are submitted to the Office of Management and Budget (OMB) for consideration. For the 2018 revision, the SOCPC Committee began planning in early 2012, and expects to solicit public input through an initial Federal Register notice to be published by the end of calendar year 2013. This process will lead to a proposed revision that will be available for public comment through a second Federal Register notice in early 2015 and publication of the final 2018 SOC codes, titles, and definitions in early 2017.
The revision schedule is designed to minimize disruption to data providers, producers, and users by promoting simultaneous adoption of revised occupational and industry classification systems for those data series that use both. Given the multiple interdependent programs that rely on the SOC, this is best accomplished by timing revisions of the SOC for the years following North American Industry Classification System (NAICS) revisions, which occur for years ending in 2 and 7. The next such year is 2018, which has the additional benefit of coinciding with the beginning year of the American Community Survey 5-year set of surveys that bracket the 2020 Decennial Census. Thus, OMB intends to consider revisions of the SOC for 2018 and every 10 years thereafter.

How you can help
The bulk of the information the SOCPC will use in developing recommendations to OMB is likely to come from the comments received in response to the Federal Register notices. Thus, the SOCPC encourages potential commenters to carefully review the information provided in “Input Requested by the SOC Policy Committee,” which is a section of “Revising the Standard Occupational Classification,” a larger document that more fully describes the history and structure of the SOC.
All comments should be submitted as responses to the Federal Register notices, using the submittal procedures described in the notices. This will ensure comments and recommendations are included on the dockets that the SOC Policy Committee will review.
The SOCPC encourages those interested in commenting, as well as others interested in the SOC, to monitor the SOC revision process on this website.

On January 21, 2009, the Office of Management and Budget (OMB) published a Federal Register notice detailing the final decisions for the 2010 SOC. Please refer to the PDF version available below for more detailed information.

As noted in the Federal Register notice of January 21, 2009, the SOCPC responses to the comments received are provided below.
Updating the Direct Match Title File
Overview. The Direct Match Title File (DMTF) lists associated job titles for detailed SOC occupations. Each of these titles is a direct match to a single SOC occupation. All workers with a job title listed in the DMTF are classified in only one detailed SOC occupation code. For example, because a "criminal law professor" would only be classified under 25-1112 Law Teachers, Postsecondary, the SOCPC would consider it a direct match. However, because a title such as "painter" could be classified in more than one occupation, including 27-1013 Fine Artists, Including Painters, Sculptors, and Illustrators 47-2141 Painters, Construction and Maintenance, or 51-9122 Painters, Transportation Equipment, the title "painter" is not a direct match.
Requests for additions to the DMTF. Although the SOC revision for 2010 is complete, the SOCPC will continue to serve as a standing committee and periodically consult with OMB, particularly to consider new and emerging occupations and additional titles for the DMTF. Interested parties should submit their request and materials in support of their recommendation to the SOCPC. Supporting materials should include the specific job title in question and the specific SOC code and title believed to be a direct match. The SOC is a task-based classification that does not differentiate occupations based on education or certification, but rather on the work performed. Therefore, the SOCPC will require information regarding the work of individuals with that particular job title. Once all of the materials have been received, the SOCPC will consider the activities involved in the specific job, and whether these activities are unique to that job.
All submissions must coincide with the SOC Classification Principles. The SOCPC encourages individuals and organizations to recommend additions to the DMTF by sending an email with the supporting material described above to firstname.lastname@example.org. Requests will be accumulated throughout the year and presented to the entire SOCPC for approval on a quarterly basis.

- Selected crosswalks are available from the National Crosswalk Service Center (NCSC), a federally-funded national clearinghouse for classification information about occupations, training programs and industries. The NCSC has been operated by the State of Iowa since 1983 under a series of grants from federal agencies. Funding for the Center has been provided by the Employment and Training Administration, U.S. Department of Labor since 1996. The NCSC provides specialized tools (files, reports, software) and technical assistance to users and producers of occupational information.
