The hierarchical model starts with six domains, describing the day-to-day aspects of the job and the qualifications and interests of the typical worker. These distinguishing characteristics of an occupation are described by the O*NET Content Model, which encapsulates the key features of an occupation into a standardized, measurable set of variables called 'descriptors'.

The database also provides the basis for our Career Exploration Tools, a set of valuable assessment instruments for workers and students looking to find or change careers.Įvery occupation requires a different mix of knowledge, skills, and abilities, and is performed using a variety of activities and tasks. Information from this freely available database forms the heart of O*NET OnLine, the interactive application for exploring and searching occupations. The database is continually updated by surveying a broad range of workers from each occupation. Central to the project is the O*NET database, containing information on hundreds of standardized and occupation-specific descriptors. The O*NET program is the nation's primary source of occupational information.
