Lexile Measures and The Common Core State Standards

MetaMetrics is an "Endorsing Partner" of the Common Core State Standards Initiative. This historic endeavor was sought to establish a clear set of K-12 standards that would ensure all students graduate from high school "college and career ready." Initially, 48 states, 2 territories and the District of Columbia signed on.

The teams charged with drafting the Common Core Standards asked that MetaMetrics share collective research on text complexity and the reading demands of college, careers and life in general. This research was conducted over the past 20 years using our widely adopted Lexile® Framework for Reading and is embodied in much of Common Core's Appendix A. Today, Lexile measures are used at the school level in all 50 states, and 20 states report Lexile measures statewide on their year-end assessments. Each year, more than 30 million Lexile measures are reported from reading assessments and programs, representing over half of U.S. students.
