With the release of the O*NET 25.1 Database in November 2020, O*NET Web Services will transition to the O*NET-SOC 2019 taxonomy. This taxonomy, based on the 2018 SOC, introduces several changes to the occupations returned by our services. It includes 1,016 occupational titles, 923 of which represent O*NET data-level occupations. For more information on these changes, see the O*NET-SOC Taxonomy page at the O*NET Resource Center.
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.
