New Partnerships Increase Use of Quantile Measures

A series of new partnerships have greatly expanded the reach of the Quantile Framework for Mathematics. In the last year, Quantile measures have been added to Pearson’s aimswebPlus and Istation’s ISIP Math. Quantile measures have also become available through state assessments in Kansas and to the 15 member states of the Smarter Balanced Assessment Consortium. These new partnerships are in addition to the numerous state level assessments and assessment products that already report student mathematical ability in Quantile measures, including Kentucky’s K-PREP, North Carolina’s NC READY, Curriculum Associates i-Ready, HMH Math Inventory and Imagine Math. Also this year, new materials and textbooks from Pearson, McGraw-Hill, Origo Publishing and Big Ideas Learning have been calibrated to the Quantile scale, adding to the dozens already featuring Quantile skill or concept measures.

Quantile measures accurately match students with instructional materials by measuring both mathematical capability and the complexity of mathematical skills and concepts on the same developmental scale. There are two types of Quantile measures: a measure for students and a measure for mathematical skills and concepts. The Quantile student measure describes what the student is prepared to learn next. The Quantile skill or concept measure describes the difficulty, or demand, in learning that skill or concept. Both measures are represented as a number followed by the letter Q (e.g., 640Q) on the Quantile scale. Quantile measures can improve mathematics teaching and learning by helping educators target instruction and determine if students are on track to pass year-end assessments and succeed in college and careers.
