What's My Trait

Twenty Holland codes and UK jobs

Your three highest interest areas, in order

The interests test gives you a three-letter code: your three highest areas, highest first. O*NET describes over 900 occupations with the same codes. The twenty below are the codes that the most O*NET occupations carry, grouped by first letter, each with one line on what the combination means and UK jobs mapped from O*NET occupations with that exact code.

If your code is not here, read the page for your first letter and then your second: the first letter says most about the work, and the order of the second and third matters less than the letters themselves.

Sources and licence

Interest codes from Holland's RIASEC model as used by the O*NET Interest Profiler. The twenty codes are those carried by the most occupations on O*NET OnLine's browse by interests pages, read on 3 November 2026: 923 occupations listed, of which 490 carry a three-letter code. Codes that tied for the last places were chosen by which had UK job profiles to show. The counts describe O*NET's occupation list, not how common each code is among people, so they are not shown. UK job titles are mapped by hand from O*NET occupations with that code and link to the National Careers Service (Department for Education) job profiles; every address was checked against the service's own sitemap on 3 November 2026.
