The O*NET database contains a rich set of variables that describe work and worker characteristics, including skill requirements. Developers and other customers are encouraged to incorporate the O*NET database within their products, services, and research. This section contains an overview of the most recent database and a variety of database download options, as well as format-specific data dictionaries.
Highlights of the O*NET 29.0 Database
In the 29.0 release, 101 occupations were updated by job incumbents and occupational experts. 881 occupations have been updated by job incumbents and occupational experts to date. This release includes the following:
- Addition and update of Abilities and Skills data for 101 occupations
- Addition and update of Task Statement ratings (importance, relevance, and frequency) for 80 occupations
- Addition and update of Work Activities, Knowledge, and Work Context data for 80 occupations
- Addition and update of Training and Work Experience and Education data for 80 occupations
- Addition and update of Work Styles data for 80 occupations
- Addition and update of Job Zones data for 80 occupations
- Addition and update of Detailed Work Activities (DWAs) and linkages for 42 occupations
- Addition and update of Alternate Titles and Sample of Reported Titles for 80 occupations
Beginning with the 29.0 release, task statements are considered relevant and retained as part of an occupation’s task statement list if they have a relevance rating of 25% or higher. The minimum relevance in previous releases was 10%. This impacts the 80 occupations with updated task ratings, as well as 466 task statements across an additional 228 occupations.
The O*NET Database: A Primary Source of Occupational Information
The O*NET database has a wide variety of worker and job oriented data categories. The O*NET Content Model provides the framework that identifies and organizes this important information about work. The O*NET-SOC Occupation Taxonomy covers work performed in the U.S. economy and defines the set of occupations for which data is collected.
The O*NET Data Collection Program currently makes updates to the O*NET Database on a quarterly basis, with a primary update occurring in the 3rd quarter of each year. Listings showing data updates by category or occupation are available on the Occupation Update Summary page. See Data Publication Schedule for a listing of primary updates and collection history. Past releases of the O*NET Database are available on the Database Releases Archive page.
