In order to determine the validity of the structure and the components of the questionnaire, the main components analysis method was used with varimax normalized rotation. The most important factor in the visual-spatial perception area is the symbolization, and in the auditory part it is memory. Independent t-test was used to assess discriminant validity. Results showed that there is a significant difference between the mean scores of students with learning disabilities and normal in the learning disability test. In order to check the validity of this study, a checklist of learning disability that was completed at the same time by the mothers was used.
