The results of the reliability of each subtest by re-test showed that the reliability of abstract reasoning (r = 0.78); spatial ability reliability (r = 0.73); form-based reasoning (r = 0.74); reliability The numerical reasoning (r = 0.77); the reliability of the mental rotation (r = 0.79); verbal comprehension reliability (r = 0.74); verbal fluidity (r = 0.80) and The total reliability of the test was 0.75. Also, the results showed the validity of the test the validity were 0.71, 0.67, 0.73, 0.67 and verbal comprehension and verbal fluidity with general information test was 0.71 and 0.65.
