Accuracy of WISC-R and Raven Standard Progressive Matrices Tests in mathematical success of children with ADHD This study investigated whether Wechsler Intelligence Scale for Children – Revised Form (WISC-R) and Raven Standard Progressive Matrices (RSPM) tests can accurately predict the mathematical success of children in elementary school with Attention Deficit Hyperactivity Disorder (ADHD). Method: In this study, WISC-R and RSPM tests were performed on 150 elementary school children (25 attention deficit, 25 hyperactivity-impulsivity, 25 combined type, 75 Control) aged 6 to 10 years. In the evaluation process, children’s attitude toward mathematics was determined and their scores were recorded. Results: Children in the control group scored higher in WISC-R subtests. Also there were significant differences in some WISC-R subtests (Vacobulary, Picture Arrangement, Picture Arrangement and Coding) scores between ADHD subtypes. When the relationship between WISC-R and RSPM tests was examined using Spearman’s rank correlation coefficient, a weak but significant positive correlation was found. Conclusion: This study showed that WISC-R and RSPM tests did not predict mathematical success. Also it showed that there was no linear correlation between mathematical skills and cognitive activity speed o
