The main question of the research is whether the fifth integrated version of Wechsler Intelligence Scales for children with learning disabilities in Mazandaran province has diagnostic validity. The present research method is in the field of psychometric studies, which is a subset of the methodological research method. The research community includes all students of Mazandaran province who are studying in the first elementary school (first, second and third grade) in the 97-98 academic year and as students with learning disabilities in private and public centres under Coverage of educational-therapeutic services, consisting of 240 students with learning disabilities were selected as the sample size using purposive sampling. The measurement Instrument in this Research is the fifth integrated version of the Wechsler Children's Intelligence Scale, which has good validity and reliability.
