How Lexile leveling works

Lexile measures are based on over 30 years of research and are the most widely adopted measure of reading ability and text difficulty.

Lexile measures help educators and students select books at a level that will challenge them - not so difficult as to be frustrating, but difficult enough to encourage reading growth.
