What this measures
Holland Codes (RIASEC) is the most widely-used career-interest framework. Used by the US Department of Labor's O*NET and most career counselors. It places you on six dimensions: Realistic, Investigative, Artistic, Social, Enterprising, Conventional. Your top three letters form your Holland Code (e.g., 'IAS' = investigative-artistic-social), which maps to clusters of careers that fit your interests.
- RealisticHands-on builders, doers, mechanics.
- InvestigativeThinkers, researchers, problem-solvers.
- ArtisticCreators, designers, performers.
- SocialHelpers, teachers, healers.
- EnterprisingPersuaders, leaders, entrepreneurs.
- ConventionalOrganizers, accountants, operators.

FAQ
What are Holland Codes?
Holland Codes (RIASEC) is a career-interest framework developed by John Holland in the 1950s. It places you on six dimensions: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. Your top three letters form your 'Holland Code'. Used by O*NET and most professional career counselors.
Is this the official Holland test?
No. The official Holland Self-Directed Search is copyrighted. This implementation uses the public-domain IPIP RIASEC Markers (Goldberg) and the US Department of Labor's O*NET Interest Profiler Short. Both freely usable.
What does my Holland Code mean?
Your three-letter code (e.g., 'IAS' = Investigative-Artistic-Social) indicates the career environments where people with your interests tend to thrive. It's about what you'd enjoy day-to-day, not what you're skilled at.
How does this differ from a personality test?
Personality (Big Five) measures who you are; Holland Codes measure what you find interesting and rewarding to do. Both can predict career fit, but they capture different things.
Will this tell me what job to take?
No. It'll show you which career clusters tend to fit your interests, which is one input among many. Salary, geography, training cost, and personal circumstances all matter too.
How is RIASEC different from MBTI for career planning?
MBTI sorts you into 16 types and doesn't directly map to occupations. RIASEC was designed from the start as an occupational interest framework, Holland literally fit the six dimensions to real job environments using decades of vocational data. For career questions, RIASEC has stronger empirical support and clearer occupational signal.
Why six categories? Is this scientifically validated?
Holland derived the six types from factor-analyzing thousands of occupational interest inventories. The structure has held up across 60+ years and dozens of countries. The hexagonal model (RIASEC types adjacent on a hexagon are more similar than opposite types) is one of the most-replicated structures in vocational psychology.
Will my Holland Code change over time?
The relative ordering is fairly stable in adulthood, but the absolute strength of each interest can shift with exposure, life stage, and career experience. People in their 20s often see meaningful changes; by 30+ the code is usually steady. Retesting every 3–5 years is reasonable.
What if my top three RIASEC scores are very close?
A flat profile means your interests are evenly distributed, common among generalists, founders, and renaissance-leaning people. Career-wise it suggests you'd adapt to many environments rather than being a natural fit for one cluster. Pick on adjacent attributes (income, lifestyle, learning curve) instead of forcing differentiation.
How does this compare to the Strong Interest Inventory?
The Strong Interest Inventory (CPP/Pearson, paid) is the commercial gold standard. It uses RIASEC plus more granular occupational scales and costs $40–60 to take through a counselor. This free test gives you the RIASEC layer using the same underlying framework; you skip the proprietary occupational scales but keep the core diagnostic value.
Can I use this to pick a college major?
It's one useful input. Combine it with realistic income expectations, the job market in your geography, and your Big Five Conscientiousness (which predicts grades better than interest does). The biggest career-regret pattern is choosing a major that fits none of your top three Holland types.
What jobs match an Investigative + Artistic profile?
IA combinations tend to thrive in roles that require both rigor and creative leaps: research scientist, UX researcher, product designer, architect, data journalist, behavioral economist, design researcher. The pattern shows up among people who can't stand pure ops and can't stand pure art-school environments either.
