Lexile Measure

A book, article or piece of text gets a Lexile text measure when it's analyzed by MetaMetrics. For example, the first "Harry Potter" book measures 880L, so it's called an 880 Lexile book. The Lexile Analyzer measures the complexity of the text by breaking down the entire piece and studying its characteristics, such as sentence length and word frequency, which represent the syntactic and semantic challenges that the text presents to a reader. Many other factors affect the relationship between a reader and a book, including its content, the age and interests of the reader, and the design of the actual book. Generally, longer sentences and words of lower frequency lead to higher Lexile measures; shorter sentences and words of higher frequency lead to lower Lexile measures.

The Lexile text measure is a good starting point in the book-selection process, with these other factors then being considered. Lexile text measures are rounded to the nearest 10L. Text measures reported below 0L are reported as BR for Beginning Reader.

Here is a website to find out more about Lexile measure that we use for Scholastic Reading Counts testing.

The website has detailed information on Lexile Measure and how it is determined, Lexile measure and grade level, Lexile codes, etc.  In Quick book search you can do a search for a book to find the lexile of that book and in Find a book, you can enter the lexile range (which is typically 100 below and 50 above) to find books in that particular range by also choosing various categories such as fiction, nature, science, history, etc.  If a student doesn’t remember his/her lexile, he/she can search by grade level.  Don’t forget to watch the six-minute animated video on the basic concepts and uses of the Lexile Framework for Reading.
