The Slosson-Diagnostic Math Screener helps to identify students who are at risk for mathematics failure. The administrator can very quickly attain an overall view for an entire class when group scored by a professional or paraprofessional. In addition, the administrator is allowed to observe the procedures each student actually utilized in reaching their solutions.
Tasks of the Five Grade Ranges:
• Conceptual Math Development: Counting, geometry, measurement, time, money, fractions, percentage, decimals, and rounding.
• Math Problem Solving: One and two step application problems utilizing addition, subtraction, multiplication, and division
• Math Computation Skills: Addition, subtraction, multiplication, and division operations. Advanced levels include decimals and fractions.
The S-DMS yields standard scores and both grade and age norms/scores. Statistical interpretation is simplified through use of percentile ranks, performance ranges, and standard scores. Diagnostic interpretation is facilitated by provision of specific behavioral objectives.
Normed on 1,699 children, internal consistency and test-retest reliabilities of the total scores were in the mid .90s. Convergent validity with other commonly used math diagnostic tests and screeners were calculated at all grade levels.
Normative data is provided to convert raw scores into Standard Scores and Percentile Ranks, as well as grade scores. Higher Standard Scores (i.e. increasingly positive deviations from the means) indicate enhanced math performance. Normed on 1,699 children, internal consistency and test-retest reliabilities of the total scores were in the mid .90s. Convergent validity with other commonly used math diagnostic tests and screeners were calculated at all grade levels.
5 Grade Ranges:
Level 1:Grades 1 through 2
Level 2:Grade 3
Level 3:Grade 4 through Grade 5.4
Level 4:Grade 5.5 through Grade 6
Level 5:Grade 7 through Grade 8
