1. Lexile: One Way to Level
By: Casey Bennett

2. 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

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

5. 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
