What is a Holland code?
A shorthand for your interest profile, built from six types that John Holland described in the 1950s and refined until 1997: Realistic (working with things), Investigative (working with ideas), Artistic (creating), Social (helping), Enterprising (persuading and leading), Conventional (organizing data and processes). Your code is the one to three letters where you score highest, for example SEA or RIC. Career counselors, the O*NET occupation database, and most serious vocational tools speak this vocabulary, which is what makes the code portable: you can take it into any counseling conversation and be understood.
Can a company use this test to screen job candidates?
No, and this is a license condition, not small print. The O*NET Career Exploration Tools were built for career exploration and counseling. Using them to select personnel changes their purpose, and the O*NET Tools Developer License then requires a formal validation study under the U.S. Uniform Guidelines on Employee Selection Procedures (41 C.F.R. Part 60-3). No such study backs this version. On NOESIS the test is offered for self-knowledge and career development only, and it is marked unsuitable for recruitment. Interest scores are also easy to fake when a job is at stake, which would make the results worthless exactly where the stakes are highest.
NOESIS already has the ORVIS. Which one should I take?
They answer different questions with different vocabularies. The ORVIS has 92 items and maps eight Oregon interest scales, a finer-grained profile for people who want depth. The Mini-IP has 30 items and produces the classic six-type Holland code, the standard language of career counseling. If you want the recognized three-letter code quickly, take this one. If you want a longer, more detailed interest profile, take the ORVIS. Taking both is not redundant: the eight Oregon scales and the six RIASEC types slice the same territory along different lines.
Can 30 questions really capture my interests?
With a measurable cost, yes. The Mini-IP is the official short form of the 60-item Short-IP. In the validation study, 73% of participants got the same first letter on both forms (Cohen's kappa .73), and the median correlation between a person's 30-item and 60-item profiles was .95. The price of brevity is reliability: 0.74 to 0.81 per scale, against 0.85 to 0.90 for the 60-item form. The technical report itself recommends the longer form when accuracy matters more than speed. For a first read of your interest profile, the short form is what the Department of Labor built it to be: fast and close enough.
Will the result tell me which job to choose?
It gives you the profile and the code, not a job list. In the official U.S. tools, the code feeds a matching engine against the O*NET occupation database, filtered by preparation level; that database is specific to the U.S. labor market and is not part of this test. What the code does is order your options: it tells you which of two offers, majors, or projects sits closer to what actually attracts you. That is a filter you apply to your own market, not a verdict handed down.
Is this the official O*NET assessment?
The items are: the English version reproduces the 30 activities verbatim from the official technical report, and the scoring follows the published rules exactly. The packaging is not: the translations, the report, and this page are NOESIS additions under the O*NET Tools Developer License, and USDOL/ETA has not approved, endorsed, or tested these modifications. The unmodified English original is available free on the U.S. government's My Next Move site. What you pay NOESIS for is what the government version does not do: six languages, a full interpretive report, and the profile living alongside your other test results.
