The assessment on this page is the complete original English 30-item O*NET® Mini Interest Profiler. We retain its questions, response anchors, and six raw-score calculations. It measures vocational interests, not intelligence, skill, or suitability for employment.
The 2016 development report used a developmental dataset of 1,061 participants and a separate validation sample of 575 US adults aged 18–65, recruited through MTurk. The validation participants completed the 60-item Short Form, with the 30 Mini-IP items embedded. In Table 9 (printed p.37), Mini-IP coefficient alpha ranged from .74 to .81 across the six scales. This describes internal consistency in that sample, not a percentage of correct career predictions.
Structural analyses supported the expected RIASEC organization. One Conventional item’s wording was updated after the validation analysis; we use the final published wording, also used in the current official tool. The study does not independently validate every detail of this website, every population, or our separate guide. A 30-item measure trades some precision for brevity.
Our four planning questions, role examples, and action plans are separate editorial content. They are not part of the O*NET® instrument, do not change its scores, and have not been psychometrically validated. For an official occupation-matching experience, use the original O*NET® website.
Broader research offers useful context. Nye and colleagues’ 2012 review of 60 studies found associations between interests, performance, and persistence. Hoff and colleagues’ 2020 review of 105 studies (39,602 participants) found a modest interest-fit/job-satisfaction correlation of .19. These are associations, not evidence that taking a quiz causes a better career.
