This response lists STEM occupation types. Each occupation type contains a number of occupations that require education in science, technology, engineering, and mathematics (STEM) disciplines. The href attribute on each cluster links to a listing of all occupations in that occupation type.

STEM occupation types and occupation linkages come from the Standard Occupational Classification external site Attachment C: Detailed 2010 SOC occupations included in STEM (updated 2016).

This response lists all occupations grouped into the requested STEM occupation type. Instead of an occupation type code, developers may pass the value all to retrieve all STEM occupations. The occupation_type element indicates each result's occupation type.

Each result also includes a job_family element. O*NET OnLine uses Job Families to organize occupations within the larger occupation types.

By default, returned occupations are sorted by Job Family and then by occupation title. When the value all is used, occupations are sorted by title. You can change this by passing the optional sort parameter:

  • family - sort by Job Family (default)
  • name - sort by occupation title (default when listing all occcupations)
  • code - sort by O*NET-SOC code

The result list is paged, returning 20 occupations at a time by default. To navigate the full set of results, use the link rel="next" and link rel="prev" elements, or provide start and end parameters to jump directly to the desired results.
