About the CHC cognitive assessment
The Cattell-Horn-Carroll (CHC) theory is the most comprehensive psychometric model of intelligence, integrating six decades of psychological research. The Cattell Horn Carroll model is hierarchical: it defines 7 broad abilities at the second stratum and over 70 narrow abilities at the first stratum that together describe human intelligence. Modern intelligence batteries like the WJ-IV, WISC-V, and Kaufman scales all map their indexes onto CHC's broad and narrow abilities. The IQ EXAM CHC cognitive assessment is an online test built directly on the 7 CHC broad abilities.
Whether you want to see your cognitive profile in CHC's research-backed framework, compare your fluid and crystallized intelligence, or just take the most thorough free online cognitive assessment available, this 35-question CHC test gives you results in 25 minutes. Free to take, no signup required to start.

Frequently asked questions
What is the CHC cognitive assessment?
The Cattell-Horn-Carroll theory is the most comprehensive psychometric model of intelligence. It defines 7 broad cognitive abilities (and 70+ narrower ones). The IQ EXAM CHC assessment measures performance across all 7 broad abilities and produces a per-ability cognitive profile.
Is the CHC test free?
Yes — the CHC cognitive assessment on IQ EXAM is completely free to take. The detailed report and certificate are an optional unlock.
How long does the CHC test take?
About 25 minutes. There are 35 questions distributed across the 7 broad cognitive abilities, with no per-question timer.
What is a good IQ score?
On the 100-point scale, 100 is exactly average and about two-thirds of people score between 85 and 115. A score above 130 is considered gifted (top ~2%), and above 145 is highly gifted (top ~0.1%). Your IQ EXAM report shows exactly where you fall and your percentile rank.
What is the average IQ?
The average IQ is 100 by definition — the scale is centred on 100 with a standard deviation of 15, so most people (about 68%) score between 85 and 115.
What's the difference between CHC and tests like WAIS?
WAIS measures 4 indexes; Stanford-Binet 5 measures 5 factors; CHC defines 7 broad abilities — the most granular widely-accepted model. Modern intelligence batteries often map their indexes onto CHC's broader framework.
Do I get a CHC certificate?
Yes — after the test you can unlock an official IQ EXAM CHC certificate showing your performance across all 7 broad cognitive abilities, plus a percentile ranking.
What are the 7 CHC broad abilities?
Fluid Intelligence (Gf), Crystallized Intelligence (Gc), Working Memory (Gwm), Retrieval Fluency (Gr), Processing Speed (Gs), Visual Processing (Gv), and Auditory Processing (Ga). Each is independently assessed and scored.
Is this an official CHC test?
No — IQ EXAM is an online assessment inspired by CHC theory — the Cattell-Horn-Carroll model behind the Woodcock-Johnson cognitive tests. Full clinical CHC-aligned batteries (like the Woodcock-Johnson IV, WJ-IV) are administered one-on-one by qualified examiners. The IQ EXAM CHC test is for educational and self-assessment purposes.
