method:the scale structured the base on Thurston,s theory .The scale is consisted of seven domains:verbal ability ،verbal fluency،numder ability ،deductive reasoning ،perceptual speed،memory and spatial comprehension.The scale performanced on 513 tehranian high school students population To determain reliability ، we use testretest ،split ، half method ،kuder-Richardson، and to determain validity ، we use of content validity،criterion validity (concurent validity،predictive validity)،construct validity (factorial validity)،discriminant validity) Coefficent is 0.85،split ،method result: Test retest reliability Is 0.75، koderrechardson coefficient is 0.87.all of the reliability coefficent are dependability.The scale is valid to assess intelligence ، Concurent validity is 0.52 ،predictive validity is 3.91and has ability to differentiate between borderline ،bright and normal individual.ر
