ICAR Cognitive Sample (text items)

What it measures

The 8 text-based items of the public-domain ICAR16: verbal reasoning and letter–number series.

Condon, D. M., & Revelle, W. (2014). The international cognitive ability resource: Development and initial validation. Intelligence, 43, 52–64.

Validity & honesty

Only 8 fixed items — treat this as a spot-check, not a precise IQ estimate, and expect strong practice effects on repeats (the items never change; a long cooldown is advised). The generated Matrices and Series tests are the retest-safe alternatives.

Cadence: a retake every 90 days is advised. You can retake anytime — early retakes are scored normally and flagged in trend analysis.
