Lexile: One Way to LevelBy: Casey Bennett
What is the Lexile Framework for Reading?• A new method designed to improve reading comprehension
– Built upon 12+ years of research by MetaMetrics Inc.
• Lexile Analyzer is a software program that analyzes any text– Measures text’s syntactic complexity
– Algorithm measures vocabulary, word frequency, and sentence length
– Assigns it a numerical level or “Lexile Rating”
– Targets books on the right reading level for a child’s ability
• Linked to national standardized tests such as the SATs and Common Core State Standards– A student’s Lexile reding level can be determined from such tests

Typical Reader Measures, by Grade
Lexile Levels
Lexile Levels• Lexile database- ranges from below 200L to above 1600L
– The Lexile codes, in addition to the numerical range, are:
– AD: Adult Directed- Picture Books
– NC: Non-Conforming- Lexile measure markedly higher than is typical for the publisher's intended audience or designated developmental level of the book
– HL: High-Low- Lexile measure much lower than the average reading ability of the intended age range of its readers
– IG: Illustrated Guide- Books that consist of independent pieces or sections of text such as in an encyclopedia or glossary
– GN: Graphic Novel- Graphic novel or comic book
– BR: Beginning Reading- Lexile measure of 0L or below appropriate for the emergent reader
– NP: Non-Prose- Book comprising more than 50% non-standard or non-conforming prose such as poems, plays, songs, and recipes
Matching Reader to Text• A student’s Lexile reading level measure is determined from a reading
assessment
• Texts’ Lexile rating are determined using the Lexile Analyzer
• Reader is matched with a text of the same Lexile level- “targeted” reading experience
– Focus on a range around the number- 100L below to 50L above reported Lexile measure
– 75% of the reading material should be comprehended by the reader
– Reader will encounter some difficulty with the text but not enough to get frustrated
– Helps the reader to grow with a text that is not too easy nor too hard
– Lexile levels can be used to monitor a reader’s growth in reading ability over a period of time
Lexile Reader vs. Lexile Text Measure
How to “Lexile” a Collection cont.• Integrate Lexile measures into your library's online catalog
and book search– Lexile Titles Download
– The Lexile Book Database contains measures for tens of thousands of books from hundreds of publishers
– Separate databases for English and Spanish titles.
– Do it yourself
– Work with one of several library-automation partners who will do it for a fee.
How to “Lexile” a Collection• The Lexile leveling system has become a recent trend in many schools’ Library
Media Centers
• Option #1- Color code books by Lexile zone with spine stickers
• Option #2- Analyze Lexile distribution of student test scores– Align library books purchases with students’ abilities
– Select shelves just for high-Lexile and low-Lexile books
• Option 3#- Students receive Lexile measures at the beginning of the school year – In the library reorganized all fiction by Lexile zone
– Color-coded all nonfiction by Lexile zone\
– Create a student Lexile tracking center
– Recognize students for the growth accomplished and promote them on the "Lexile wall“
• Option #4- Have a cart in the library arranged by Lexile– Merges different collection systems and isn’t solely based on Lexile
