Theoretical Framework
This assessment is grounded in Holland's RIASEC theory (Holland, 1959; 1997), the most empirically validated model of vocational interests in occupational psychology. Holland proposed that people can be classified into six types — Realistic, Investigative, Artistic, Social, Enterprising, and Conventional — and that career satisfaction arises from congruence between a person's type and their occupational environment. Our 20 questions systematically probe each of these dimensions through work style, interest, ability, and values lenses.
The values and environment dimensions draw on Super's Life-Span, Life-Space theory (Super, 1980; 1990), which proposes that career development is a lifelong process shaped by self-concept and life roles. Questions assessing work environment preference and life design reflect Super's validated Work Values Inventory constructs.
The Social Cognitive Career Theory (Lent, Brown & Hackett, 1994) underpins the skills and self-efficacy dimension of the test. SCCT posits that self-efficacy beliefs and outcome expectations — not just interests — are central to career choice. Our ability-focused questions are calibrated against SCCT's established predictors of career persistence and satisfaction.
The sub-profession scoring model uses weighted composite scores derived from validated occupational congruence research (Rounds & Day, 1999) and the O*NET occupational information framework, which classifies hundreds of occupations by interests, skills, and work values across standardised dimensions.
Question Design
Questions were designed to minimise social desirability bias and framing effects by presenting all options as equally valid lifestyle or preference choices rather than ability tests. This follows the methodology of the Strong Interest Inventory (Harmon et al., 1994) and the Campbell Interest and Skill Survey (Campbell, 1992), both of which avoid deficit framing in vocational assessment.
The test uses a forced-choice single-selection format per question. Forced-choice designs have been shown to reduce acquiescence bias and produce more discriminating occupational profiles compared to Likert-scale alternatives (Brown & Maydeu-Olivares, 2011).

Theoretical Framework
This test is built on Holland's RIASEC theory (Holland, 1997): people and study environments can both be described by six interest types, and students do best where the two fit. Research backs this up: students whose interests match their subject tend to perform better, stay on their course and graduate on time (Allen & Robbins, 2010), and a meta-analysis of over 60 years of research found that interest fit predicts performance and persistence better than interest scores alone (Nye, Su, Rounds & Drasgow, 2012).
Part 1: Your Interests
Your interests are measured with the O*NET Mini Interest Profiler (Rounds, Wee, Cao, Song & Lewis, 2016), a validated 30-activity version of the U.S. Department of Labor's Interest Profiler, with reliabilities of .74 to .81 in its validation sample. The activities are reproduced word for word, as the licence requires, and your scores are compared with the instrument's published validation sample. The Mini-IP is used under the CC BY-ND 4.0 licence; O*NET is a trademark of the U.S. Department of Labor.
Parts 2 and 3: Subjects and Study Style
Favourite and strongest subjects reflect Social Cognitive Career Theory (Lent, Brown & Hackett, 1994): enjoyment and confidence in a subject shape later interests and choices, and school subjects often determine entry requirements. The study-style questions ask which course formats you would prefer, such as theory or application, essays or projects, labs or placements. They are deliberately not "learning styles", a popular idea that research does not support (Pashler, McDaniel, Rohrer & Bjork, 2008).
How Subject Areas Are Matched
Each of the 25 subject areas has a three-letter Holland code, based on the interest profiles of the occupations it most often leads to (O*NET) and on Smart, Feldman & Ethington's (2000) classification of academic disciplines. Your match combines interest fit (60%), subject fit (25%) and study-style fit (15%). These weights are our own design choice, reflecting the much stronger evidence behind interest fit. Results are a starting point for exploration: entry requirements vary by country and university, so always check them directly.

Theoretical Framework
This test measures the Big Five personality traits: Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Openness/Intellect. The Big Five emerged from decades of research into how people describe one another across languages (Goldberg, 1992) and is the most widely replicated model of personality in psychology.
We use the Mini-IPIP (Donnellan et al., 2006), a validated 20-item questionnaire with four statements per trait, drawn from the public-domain International Personality Item Pool (Goldberg et al., 2006). The statements and their order are used exactly as published, because changing them would undermine the validation evidence. Answers use the standard IPIP five-point accuracy scale.
How Your Scores Are Compared
Your trait scores are compared with a nationally representative sample of 15,471 young adults (Baldasaro, Shanahan & Bauer, 2013), and shown as percentiles. Teenagers tend to score a little lower than adults on Conscientiousness and Agreeableness, and personality keeps developing well into adulthood (Roberts, Walton & Viechtbauer, 2006), so younger users should read their results as a snapshot rather than a verdict.
Short questionnaires trade some precision for speed: each Mini-IPIP scale has a reliability of roughly .62 to .77 across studies. Your profile name summarises your most distinctive trait in plain language; it is not a scientific "type", because the Big Five are continuous dimensions.
Links to Work and Careers
Conscientiousness is the most consistent personality predictor of job performance across occupations (Barrick & Mount, 1991) and of academic performance (Poropat, 2009). Emotional Stability, Extraversion and Conscientiousness are the traits most related to job satisfaction (Judge, Heller & Mount, 2002). Meta-analyses also link Openness with Artistic and Investigative interests, and Extraversion with Enterprising and Social interests (Larson, Rottinghaus & Borgen, 2002; Barrick, Mount & Gupta, 2003). These links are modest, which is why the career suggestions point you to the Career Matches test rather than replacing it.
