What is a Quantile measure?
A Quantile is a unit of measure on the Quantile scale. A Quantile measures mathematical achievement and concept/application solvability similar to the way a Lexile measures reading ability and text difficulty. A Quantile measure is depicted by a number followed by a Q (e.g., 650Q). The Quantile Framework spans the developmental continuum from kindergarten mathematics through the content typically taught in Algebra II, Geometry, Trigonometry and Pre-calculusfrom Emerging Mathematician (OQ and below) to above 1400Q. A child with a Quantile measure of 500Q is likely to be ready for instruction of mathematics problems at a demand level of 500Q.
