Side-by-side comparison
| Cattell | CHC | |
|---|---|---|
| Full name | Cattell Culture Fair Intelligence Test | Cattell-Horn-Carroll cognitive battery |
| Year introduced | 1940 | CHC theory formalized 1990s |
| Target audience | All ages | All ages depending on subtest |
| Duration | 30 minutes | 40–90 minutes |
| Format | Paper or proctored | Varies by implementation (can be online or clinical) |
| Scoring | Mean 100, SD 24 — so Mensa threshold on Cattell is 148, not 132 | Multi-factor profile across broad abilities (Gf, Gc, Gv, Gsm, etc.) |
| Strengths | Designed to minimize cultural loading | Most theoretically grounded framework; produces a rich cognitive profile rather than a single number |
| Weaknesses | Different SD scale than Wechsler; scores are NOT directly comparable | Less well-known to the general public; interpretation requires training |
| Best for | Cross-cultural testing, historical comparison | Educational assessment, cognitive strength/weakness profiling |
