Production Database — O*NET® 18.1

The O*NET database contains several hundred variables that represent descriptors of work and worker characteristics, including skill requirements. It is provided here to enable product developers to incorporate the O*NET database into their products. This section contains the database, the data dictionary, technical documentation, and other information to support such product development.

Production versus Development Database

For clarity and distinction, the database used in O*NET OnLine is called the production database. It is currently O*NET 18.1 and is available for download below. Those wishing to utilize the database currently in use in O*NET OnLine should use this version.

The most recently developed database is referred to as our development database. This is the version of the database that will be implemented in the next update of O*NET OnLine scheduled for fall 2014. However, an application developer or other user may choose to begin using the O*NET 19.0 database at any point. The 19.0 files can also be used in planning for any future update of existing products or in developing new products. This version is available for download from our Development Database page.

Highlights of the O*NET 18.1 Database

Released in March 2014, this release includes newly developed Detailed Work Activities (DWAs) data, along with broader Intermediate Work Activities (IWAs) and a separate set of Green DWAs. See the Work Activities Project Technical Report for more information on the development of the DWAs, and the Data Dictionary 18.1 for details on the new database files.

The 18.1 release contains five new files related to Detailed Work Activities. All other files are unchanged from the 18.0 database, released in July 2013.

Highlights of the O*NET 18.0 Database

105 occupations were comprehensively updated, bringing the total to 921, in this fourteenth major update from the O*NET Data Collection Program. Highlights of this update include:
