About CAIT-NV
CAIT-NV uses IRT in conjunction with adaptive testing to measure nonverbal intelligence quickly and accurately. The test dynamically adjusts to your performance, minimizing measurement error and administration time. The assessment is now half as short and as accurate if not more than before by using all the available information at the item level. In fact, the test works to maximize the correlation with g based on your performance.

Item Response Theory
Mathematical framework that models the relationship between latent traits and item responses for precise measurement.
Adaptive Algorithm
Real-time difficulty adjustment based on response patterns, optimizing measurement accuracy.
Nonverbal Paradigm
Language-independent assessment of fluid intelligence through abstract pattern recognition.
Precision Measurement
Statistical convergence on ability estimate with minimal standard error.
