The Lexile® Framework for Reading

A popular method used by schools to measure a student reader’s ability is Lexile level or a Lexile Measure. A valuable tool for teachers, parents, and students, it serves two unique functions: to measure how difficult a text is or a student’s reading ability level. Read on to understand how it works.

One Book Does Not Fit All…

Although children may be the same age, but their reading levels can vary!

How Can That Be?

Reading proficiency is being able to read the text expected for a year level. Just like shoes, one size does not fit all – which is pretty much how our reading levels are.The Lexile® Framework for Reading is a scientific approach that places both the reader and text on the same developmental scale, making it easy to connect your child with books targeted to their reading ability.

How is Lexile Text Complexity Analyzed?

Through the Lexile® Analyzer, text complexity is determined based on difficulty of sentence level (Syntactic) and word level (Semantic).The algorithm that is used to determine the Lexile® measure of a book or piece of text is now enhanced to provide more precise measurement of materials read in K-2 classrooms.As a result, the nine-variable model provides "early-reading indicators" that help identify important text features.Thease are categorized into four early-reading indicators and assigned a level of difficulty for typical K-2 books (see examples below):
