Revising the SOC for 2018 was a multi-year process, during which the interagency SOC Policy Committee (SOCPC) formulated recommendations for revisions that were submitted to OMB for consideration. For the 2018 revision, the SOCPC began planning in early 2012. The SOCPC encourages commenters interested in more background on the SOC to carefully review information provided before publication of the May 22, 2014 Federal Register notice 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.

On May 22, 2014, OMB published a Federal Register notice announcing review of the 2010 SOC manual for revision in 2018 and soliciting public comment on the proposed revision of the 2010 SOC Classification Principles; the intention to retain the 2010 SOC Coding Guidelines; the intention to retain the 2010 SOC Major Group Structure; the correction, change, or combination of selected 2010 SOC detailed occupations, and inclusion of new detailed occupations. The comment period for this notice closed on July 21, 2014. On July 22, 2016, OMB published a second Federal Register notice seeking public comment on the recommendations for the 2018 SOC, including the 2018 SOC structure and preliminary definitions. The third and final Federal Register notice announcing the 2018 SOC was published on November 28, 2017.

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 51-9124 Coating, Painting, and Spraying Machine Setters, Operators, and Tenders, the title "painter" is not a direct match.

Requests for additions to the DMTF. Although the SOC revision for 2018 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 soc@bls.gov. Requests will be accumulated throughout the year and presented to the entire SOCPC for approval on a quarterly basis.
