The Lexile Framework

The Lexile Framework for Reading was developed by MetaMetrics (www.metametricsinc.com), a privately-held educational measurement company, whose reading level measurements are widely used in the K-12 system. This Lexile framework is a scientific approach to reading measurement that matches readers to text. The Lexile Framework measures both reader ability and text difficulty on the same scale, called the Lexile scale. This approach allows educators to manage reading comprehension and encourage reader progress using Lexile measures.

Lexiles give educators the confidence to choose materials that will improve student reading skills across the curriculum. Tens of thousands of books and tens of millions of articles have Lexile measures, hundreds of publishers Lexile their materials and all major standardized tests can report student reading scores in Lexiles.
