APS periodically completes formative assessments that are nationally normed in order to support individual student needs. The Math Inventory (MI) assessment is a low-stakes, classroom-based, computer-adaptive universal screener and progress monitoring tool. The MI assesses student performance in five strands of mathematics: Number and Operations, Geometry, Measurement, Algebra, and Data Analysis and Probability. Student results are reported using a measure called the Quantile, which indicates how well a student understands mathematical skills and concepts along a developmental continuum. Math Inventory is currently designed to measure a student’s location on the Quantile Framework within their grade-level. While the assessment also spans grades, the precision of the tool is focused inside of grade-level content.
