Lexile and Quantile Frameworks

The Lexile and Quantile Frameworks are systems that measure both student reading and math ability, as well as the complexity of text and mathematics. The Lexile Framework links student reading ability with texts that are appropriately challenging. The Quantile Framework works similarly for mathematics, matching student capacity to the difficulty level of math. The Vermont Agency of Education has partnered with MetaMetrics to offer statewide, no-cost access to the Lexile and Quantile Frameworks and their associated resources to all Vermont school districts. 

As a Lexile and Quantile State Partner, Vermont will receive student-specific Lexile and Quantile measures on Vermont Smarter Balanced Assessment scores starting with the 2020 testing cycle. Educators will be able to use the Lexile and Quantile measures from the Smarter Balanced Assessment scores to target resources and instruction to help their students improve. 

The Lexile Framework for Reading

The Lexile Framework for Reading uses Lexile measures to help educators and parents find reading materials at each student's unique reading level, engaging students in learning by ensuring they comprehend their reading materials and monitoring their progress over time. Educators can use Lexile measures to personalize student learning, differentiate their instruction and better communicate with parents.

What is a Lexile Measure?

There are two kinds of Lexile measures: Lexile reader measures and Lexile text measures. Lexile reader measures describe how strong a student’s reading is. Lexile text measures describe how difficult, or complex, a text like a book or magazine article is. Lexile measures are expressed as numbers followed by an “L” (for example, 850L), and range from below 0L for beginning readers and text to above 1600L for advanced readers and text. Comparing a student’s Lexile measure with the Lexile measure of what they are reading helps gauge the “fit” between a student’s ability and the difficulty of text.

The Quantile Framework for Mathematics

The Quantile Framework for Mathematics evaluates the difficulty of mathematical skills and concepts as well as a student’s ability to learn new mathematical concepts. Each of these measures are on a single scale so that the skill demand and student ability can be matched for targeting instruction.

What is a Quantile Measure?

Similar to Lexile measures, there are two types of Quantile measures: a measure for students and a measure for mathematical skills and concepts. The student measure describes what mathematics the student likely already understands and what the student is ready to learn in the future. The skill measure describes the difficulty, or demand, in learning the skill. Quantile measures are expressed as numbers followed by a “Q” (for example, 850Q) and range from emerging mathematician (below 0Q) to above 1600Q. The Quantile Framework spans the developmental continuum from the content typically taught in kindergarten to Algebra II, Geometry, Trigonometry and Pre-calculus. Quantile measures help educators and parents target instruction and monitor student growth toward learning standards and the mathematical demands of college and careers.

Lexile & Quantile Hub: Instructional and Planning Resources

Teachers employed by Vermont Supervisory Unions and School Districts have full access to the Lexile & Quantile Hub. Families and students will also find free tools on the Hub to support their learning and career aspirations. The Hub's many resources include:

Lexile Find-A-Book, which identifies books with specific Lexile measures

The Lexile Analyzer, which provides Lexile scores for custom text

Lexile WordLists to address vocabulary gaps and prepare students for the academic words they will encounter in their learning

The Lexile Career Database and the Quantile Career Database help educators, parents and students identify the reading and mathematics ability needed for entry into a desired career

The Quantile Math Skills Database containing targeted, free resources appropriately matched to students by Quantile measure and math content

The Quantile Teacher Assistant, which helps educators locate resources that can help with instruction and identify those skills that are most relevant to the topic of daily instruction

Quantile Math@Home, which contains targeted, free resources for students and families appropriately matched to students by Quantile measure and math content

Watch this video, An Introduction to the Lexile and Quantile Hub, to learn more about how to use these resources.
