Perceptual-motor deficits are common in children with intellectual disabilities and have a profound impact on their ability to perform age-appropriate self-care and academic tasks. The purpose of the present study was to investigate the relation between the Beery Test of Visual-Motor Integration (VMI) (Beery, 1989) and the Wechsler Intelligence Scale for Children-III (WISC-III) (Georgas, Paraskevopoulos, Bezevegis, Giannitsas, 1997) in a sample of 40 children with mild intellectual disability. The results in our study indicated that there were significant Pearson correlations ranged from.39 to.52 between the VMI and the WISC-III, showing higher correlations between the WISC-III Performance IQ and the VMI. Finally, regression analysis was applied to evaluate the relation of the WISC-III scores to the VMI scores. It seems that certain Wechsler scales have predictive power to VMI performance. Correlations between the VMI and measures of intelligence and academic achievement are at best moderate; thus, its use for important decisions such as obtaining needed services and evaluating the effectiveness of educational interventions is unwarranted.
