The purpose of the present research is to restructure, validate, make reliable and normalize math self concepts scale. in testing research, 812 students from Malards high school were participated. Method:In this study, the items of math self concept restructured scale was analyzed with discriminant index and loop method. The reliability of scale was investigated with split-half method and coefficient alpha, then construct validity, criterion validity and discriminant validity were investigated. Investigating construct validity, we use factor analysis , and also investigating discriminant validity, math anxiety scale (from Betz) was used, because there is a negative relation between math self concept and math anxiety. Investigating discriminant validity, we use a difference between 3 course of education in students. T and Z scores were used for normalization of scale. Findings:Reliability of this scale was 0/898 and discriminant validity was meaningful, that is show a meaningful difference between 3 courses and confirm discriminant validity of this scale. Result of construct- related validity shows 3 factors in this scale. The restructured scale can be beneficial for students in choosing their course of study and for measuring their affective to math.
