Free Strengths Test — find your natural aptitudes

Strengths, in this context, are natural aptitudes — clusters of ability that predict where you're likely to do well and enjoy the work. Not to be confused with skills (learned) or interests (what draws you). This test covers five main clusters:

• Analytical — reasoning, problem-solving, systems-thinking
• Creative — divergent thinking, aesthetic sense, generation of new ideas
• Technical — mechanical understanding, spatial reasoning, hands-on aptitude
• Social — reading people, communicating, cooperation
• Organisational — planning, sequencing, follow-through

The five clusters above roughly map onto the Cattell-Horn-Carroll (CHC) model — the dominant framework in modern cognitive psychology. CHC identifies broad and narrow abilities (Gf fluid reasoning, Gc crystallised knowledge, Gv visual-spatial, Gs speed, Gsm working memory, Gq quantitative), each of which has published predictive validity for job performance.

General cognitive ability alone is the single strongest predictor of job performance across most occupations (Schmidt & Hunter 1998, updated Sackett et al. 2017; r ≈ 0.51). Specific abilities sharpen the fit further — someone strong in Gf but weak in Gc will thrive in different careers than the reverse.

The commercial 'Strengths Finder' (CliftonStrengths, Gallup) charges $20–$60 for a 34-strength assessment. Ours is free and covers the same cognitive-and-behavioural surface. Both are useful; if you can afford CliftonStrengths and want their specific taxonomy, take it — the frameworks are complementary, not competing.
