The NAIT is an untimed, computerized, self-scoring IQ assessment consisting of 120 items designed to measure cognitive ability beyond the range of standard IQ tests.
These items cover numerical, verbal, logical, abstract, and spatial reasoning and are approximately arranged in order of increasing difficulty.
While not a replacement for professionally administered psychological evaluations, the NAIT is intended as a complementary tool for measuring cognitive ability.
Note: The NAIT is a standalone computer program that runs only on Windows 10 & 11. (Approx. 780 MB compressed)
