| | | | | | | | Availability | | Classification | | Short Description of Instrument | The KeyMath-3 Diagnostic Assessment is used to assess a subjectâ€™s ability to understand and apply mathematical concepts. Five subtests assess basic concepts (Numeration, Algebra, Geometry, Measurement, Data Analysis and Probability); three subtests test operations (Mental Computation and Estimation, Written Computation: Addition and Subtraction, Written Computation: Multiplication and Division); and two subtests are devoted to applying concepts (Foundations of Problem Solving and Applied Problem Solving). The KeyMath-3 is individually administered and ranges from 30 to 90 minutes for the entire battery of tests, depending on the student's grade level. Select subtests may be administered if a professional is interested in a particular area of the studentâ€™s ability. | Scoring | Standard scores (M=100, SD=15), scale scores, percentiles, and grade/age equivalents are given for the Total Test, 3 areas, and 10 subtests. Examiner should have formal training in mathematics and test interpretation. This assessment has two versions that can be administered (by alternating versions) every three months. | References | Wagner, R., Torgesen, J., and Rashotte, C. (1999).
