Frequently Asked Questions

When and how was the information in the O*NET Database collected?

In order to keep the O*NET Database updated, the National Center for O*NET Development has an ongoing data collection program aimed at identifying and maintaining current information on the characteristics of workers and occupations. The information that populates the O*NET Database is collected from three primary sources: job incumbents, occupational experts, and occupational analysts. See O*NET Data Collection for an overview of the project, or visit the Data Collection Program external site website. For a listing of occupations with updated data along with the date they were last updated, see Occupations Populated with Updated Data.
