On November 17, 2020, O*NET released its 25.1 database by adding, removing and updating Standard Occupational Classification (SOC) Codes.

The O*NET database is a primary source of occupational information. It contains a rich set of variables that describe work and worker characteristics, including skill requirements. The database includes information on skills, abilities, knowledge, work activities, and interests associated with occupations. This information can be used to facilitate career exploration, vocational counseling, and a variety of human resources functions, such as developing job orders and position descriptions and aligning training with current workplace needs. O*NET is developed under the sponsorship of the U.S. Department of Labor/Employment and Training Administration (USDOL/ETA) through a grant to the North Carolina Department of Commerce.

The O*NET 25.1 Database is a special release that incorporates the O*NET-SOC 2019 taxonomy structure. The O*NET-SOC 2019 Taxonomy structure has been revised based on the transition to the 2018 SOC. The O*NET 25.1 Database, which incorporates the new O*NET-SOC taxonomy, includes 1,016 occupational titles, 923 of which represent O*NET data-level occupations. The new O*NET-SOC 2019 structure also includes four cybersecurity-related new and emerging occupations. Attached below is the snapshot of the O*NET-SOC 2019 taxonomy structure.

Data from the O*NET 25.0 database (O*NET-SOC 2010) has been incorporated into the new O*NET-SOC 2019 taxonomy, including the new O*NET-SOC codes, titles, and descriptions. In the 25.1 release, taxonomy-related updates include:

  • Addition of 62 O*NET-SOC 2019 occupations
  • Update of O*NET-SOC codes, titles, and/or descriptions for 345 occupations
  • Addition and update of Task Statements for 127 occupations
  • Addition of Abilities, Skills, Work Activities, Knowledge, and Work Context data for 53 occupations

  • Addition and update of Detailed Work Activities (DWAs) and linkages for 127 occupations
  • Addition and update of Alternate Titles and Sample of Reported Titles for 127 occupations
  • Addition and update of Technology Skills and Tools Used for 98 occupations


Several general changes to the O*NET-SOC taxonomy were included as a result of changes made to the SOC taxonomy. Some of them are listed below:
