Understanding Lexile® Measures
The Lexile Framework® for Reading is a scientific approach to measuring both reading ability and the text complexity of reading materials on the same developmental scale.
Educators use Lexile measures to match students with text, putting them on the path to success in school, college and careers.
Lexile measures make it easy for educators to:
- Personalize learning.
- Measure student growth.
- Communicate with parents about their child’s progress.

Matching Readers With Text
Materials are in your student's reading comprehension “sweet spot“ when they are 100L below to 50L above their reported Lexile reading measure.
