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.
