Vocation
Matrix

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.

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).
