The Lexile Framework for Reading is a system used to match students with texts (books, articles, and other reading material), regardless of grade level. It takes a scientific approach to measuring reading levels. Its numeric measures can apply to both reader and text:
Lexile text measures reflect the readability of an individual book based on an analysis of word frequency, sentence length, and text complexity.

As a learner of English as a second language, you may find the Lexile scale a useful tool. When you know the Lexile score of an English book that you can comfortably read, you can pay attention to the Lexile score of the next book you choose to read in order to provide yourself with a reasonable challenge, instead of a text that may be too challenging. This can help make your learning practice less frustrating.
A Lexile score is a number, followed by the letter L. In general, the lower the number is, the easier the reading level is. However, some books containing more advanced concepts can still have a fairly low Lexile score, if they were written in clear, simple language.
Since most Lexile Scores used in the United States are used in our public school system, the scores are often listed as a range, with each school grade (year) being associated with an increasingly higher Lexile score:
The 'BR' in the first column stands for 'Beginner Reader'.
Below is a table demonstrating the Lexile levels that certain professions require, as well as the Lexile scores of important documents that adults encounter in their daily lives:
If a book is fairly simple (for early readers, or kindergarten through 12th grade), you can enter a book's information into the Lexile 'Find a Book' tool
