The table shows the 50 largest of 63 occupations with this code, ordered by U.S. employment.

Median wage is the employee annual median from BLS OES; it excludes self-employed workers and owners. “Not published” means BLS does not publish a median for that occupation — it is not zero.

“—” means O*NET does not publish a typical education level for that occupation; in O*NET Database 31.0 this field does not cover every occupation, though every row on this page has one. Where a level is given, it is the most common category in O*NET's education data, translated.

Wages and employment come from BLS OES, which publishes them by 6-digit SOC occupation. Several O*NET occupations can sit under one SOC code and share the same estimates — that is why some rows show identical wages and employment.

Of the 50 rows on this page, 3 are not a wage BLS publishes for that occupation itself: 3 use the number for the successor SOC code that absorbed the occupation, and 0 use the broader group BLS reports them under. The remaining rows are the median BLS publishes at the occupation's own 6-digit SOC level.

What these occupations mean

Every O*NET occupation carries an interest profile: six shares, one per RIASEC direction. O*NET turns that profile into the occupation's Interest High-Point (IH) code with the variable high-point rule: take the directions whose share is above .17, highest first, up to three (Rounds et al., 1999; Step 3 of the 2023 O*NET report “Using Machine Learning to Develop Occupational Interest Profiles and High-Point Codes”). That is why a code can have one, two or three letters. This page reports the codes as O*NET published them — the list describes these occupations, not you.

Your own code is generated by this product from your questionnaire scores, with a different rule: the three highest directions, with ties broken in a fixed order. The two sides also measure different things — the questionnaire asks what you like doing, while an occupation profile measures how much of that interest content the work involves. No study equates the two.

Three honest notes

The occupation-side profiles are machine-generated: O*NET derived them with machine learning from work activities and related data (see the 2023 report “Using Machine Learning to Develop Occupational Interest Profiles and High-Point Codes”), not from analyst ratings.
Even where an interest code carries some predictive signal, it is weak: it cannot tell whether a particular person will do a job well, and it does not predict income. An occupation-level profile also hides the differences between people doing the same job.
Interests change with experience — courses, projects and internships can move them. A code is a snapshot, not a fixed trait.

Find your own code

The 60 items of the O*NET® Interest Profiler Short Form (adapted by this product) produce your own code and the occupations with the closest interest profiles, with the same U.S. wage data.
