Abstract EN

This study aimed to reveal the psychometric properties of Reynolds' test of adaptive non-verbal intelligence where the descriptive method was used, on a sample of secondary school students in Tabuk city, which consisted of (936) male and female students, they were chosen by the stratified random method.

the results indicated that the reliability coefficient of the test items using the internal consistency method ranged from (0.23) to (0.70), and the reliability coefficient for the test as a whole by using Cronbach's alpha method was (0.96), and it reached (0.96) by using the split-half method.

while the validity of the items (the discrimination coefficient for each item), the correlation coefficients ranged from (0.19) to (0.68), and the correlation coefficients between each dimension and the other dimensions, and each dimension and the total score of the test ranged from (.96) to (.99).

as for the criterion-related validity, the value of the correlation coefficient between the total score of the Reynolds test of non-verbal adaptive intelligence and the CFT 20-R was (0.85).

the results also indicated that the scale items had appropriate difficulty and discrimination coefficients.

the results also showed that there were statistically significant differences in performance on the test due to the gender variable, and that there were no statistically significant differences in performance on the test due to the grade variable, and norms were derived to explain the scores on the test.

the study concluded with a number of recommendations, including: conducting other : using the Reynolds adaptive intelligence non-verbal scale to identify and measure intelligence among secondary school students, after ensuring that it has a high degree of reliability and validity.
