The O*NET-SOC 2019 taxonomy structure has been revised based on the transition to the 2018 SOC. The new O*NET-SOC taxonomy includes 1,016 occupational titles, 923 of which represent O*NET data-level occupations.
A technical report, Updating the O*NET-SOC Taxonomy: Incorporating the 2018 SOC Structure, is available which describes the new O*NET-SOC 2019 taxonomy structure. The overall relationship between the O*NET-SOC 2019 and the 2018 SOC is summarized. Code, title, or description changes that occurred from transitioning to the new 2018 SOC structure are detailed in the report. The new O*NET-SOC 2019 structure also includes four cybersecurity-related new and emerging occupations.
The O*NET Program has initiated the collection of O*NET data for new or substantively revised O*NET-SOC 2019 occupations. The O*NET 25.1 Database release will incorporate the O*NET-SOC 2019 Taxonomy structure. The release of this database is currently scheduled for November, 2020. In addition, at that time, the O*NET websites and O*NET Web Services will transition to the new structure. This release schedule takes into account the implementation schedules for the 2018 SOC
of related data on occupations from the Bureau of Labor Statistics and the Census Bureau.
To help O*NET Web Services users with the upcoming taxonomy transition, Taxonomy Services are now available to enable developers to connect occupational data between existing systems based on the O*NET-SOC 2010 taxonomy, and the future O*NET-SOC 2019 taxonomy-based O*NET Web Services.
The 2018 SOC
has been published by the Office of Management and Budget. See the Standard Occupational Classification Manual, United States, 2018
(PDF) and the 2018 SOC Implementation Schedule
for the Bureau of Labor Statistics and other federal agencies.
The O*NET Program is transitioning the O*NET-SOC 2010 taxonomy to the 2018 SOC, creating the O*NET-SOC 2019. The first step of this transition was the development of a crosswalk between the O*NET-SOC 2010 taxonomy and the 2018 SOC. The crosswalk is published for download and integrated within O*NET OnLine's SOC Crosswalk Search and within O*NET Web Services.
The February 2011 release of the O*NET 15.1 database (O*NET-SOC 2010) represented the fourth major change to the taxonomy. The taxonomy was revised based on the transition to the 2010 SOC. Details of this update and implementation of the O*NET-SOC taxonomy can be found in our Updating the O*NET-SOC Taxonomy: Incorporating the 2010 SOC Structure report.

This structure also included new and emerging (N&E) O*NET-SOC occupations identified by research focused on new workforce requirements, including changes in technology, society, law or business practices, which led to new and emerging occupations in the United States. A detailed description of the N&E effort is available in the New and Emerging (N&E) Occupations Methodology Development report. The O*NET-SOC 2010 taxonomy included a total of 152 N&E occupations identified using this process.
The June 2009 release of the O*NET 14.0 database (O*NET-SOC 2009) represents the third major change to the taxonomy. As a product and result of the New and Emerging Occupations research, 153 new and emerging (N&E) occupations identified within 17 in-demand industry clusters were added to the O*NET-SOC taxonomy. The revised taxonomy included 1102 occupational titles, 965 of which represented O*NET data-level occupations. Details of this update and implementation of the O*NET-SOC taxonomy can be found in our New and Emerging Occupations of the 21st Century: Updating the O*NET-SOC Taxonomy report.
The June 2006 release of the O*NET 10.0 database (O*NET-SOC 2006) incorporated the second major change to the taxonomy. Details of this update and implementation of the O*NET-SOC taxonomy can be found in our Updating the O*NET-SOC Taxonomy report. The O*NET-SOC 2006 taxonomy included 949 occupational titles, 812 of which represented data-level occupations.
As required by the mandate from the Office of Management and Budget (OMB)
, the O*NET taxonomy was converted to one that was SOC-based in 2000 (O*NET-SOC 2000). For more information about the SOC transition, see our Transitioning O*NET to the Standard Occupational Classification report.
The initial O*NET database release (O*NET 98) was based on the occupational classification used by the BLS Occupational Employment Statistics (OES)
program at that time. This OES-based taxonomy was developed and released prior to the update to the Standard Occupational Classification (SOC)
The established Occupational Code Assignment (OCA) process enables users to submit occupational information, and request assistance in identifying a matching O*NET-SOC code and title. In cases where an existing occupational code and title cannot be identified, the submitted information is reviewed and utilized in identifying occupations that eventually might be added to the O*NET-SOC system.
