The test consisted of 23 geometric designs and each of the designs was assessed through a definite criteria and was scored as errors(weakness) and accuracies(strength).For adaptation and standardization of this test, at first step the examinerʹs manual and the test items were translated into Farsi.

Internal consistency coefficients of the subtests were obtained by Cronbachʹs Alpha; time consistency of the subtests and compound scores were obtained by test-retest. Alpha coefficients for the compound scores were obtained by Guilford formula, which is designed for estimating the compound scores. To obtain the content validity, criterion-related validity and construct validity of the subtests and compound scores, appropriate methods were used. Findings: The results obtained ensure the applicability of this test for the evaluation of visual-motor skills of children of Tehran. Conclusion : Accordingtothe findings, this test can be used for the disorders in eye-hand coordination, the identification ofchildren with disorders in visual -motor skills.
