The results showed that: The cognitive performance scale for autistic children with savant syndrome had acceptable and reliable validity and reliability indicators. The logical validity method (arbitrators' validity) was used in validity, and the McDonald Omega coefficient and split-half methods were used in stability; where the stability value using the two methods reached (0.786- 0.835) respectively. The internal consistency between the dimensions and the total score of the scale was also calculated.
