About
CAIT-NV combines IRT with adaptive testing to measure nonverbal intelligence. Questions adapt to how you're doing, which cuts down on wasted time and improves accuracy. It's half the length of the original CAIT but more precise, since it uses all available item-level data. The algorithm specifically targets high g-loading based on your responses.
