Lexile

 

What is a Lexile® measure?

A Lexile measure represents the complexity of a text, such as a book or article.  Lexile measures are expressed as numeric measures followed by an 'L' (for example, 850L), and are placed on the Lexile scale.  The Lexile scale is a developmental scale for measuring reader ability and text complexity, ranging from below 200L for beginning readers and beginning-reader materials to above 1600L for advanced readers and materials.

NEW!  Lexile measure is now provided for books at the Grade K-2 level to allow for a greater differentiation at the beginner level.  Our previously Lexiled materials have been updated to meet the new Lexile framework.
