The Slosson-Diagnostic Math Screener (S-DMS) was designed to help identify students aged 6 - 13 years at risk for mathematics failure. The administrator can observe the procedures of each student and very quickly attains an overall view for an entire class when group administered. The S-DMS yields standard scores and both grade and age norms and scores.Internal consistency, test-retest reliability, item analysis, decision efficiency, convergent validity, and factorial validity of all five levels of the S-DMS were studied using 20 independent samples of students.
