Lexile Ranges are generated when the NWEA Reading MAP test is taken.NWEA Reading tests report Lexile®* range scores so that teachers and media center staff can help students and parents select appropriately challenging reading materials.What is a Lexile® Measure? (From the Lexile Website (www.lexile.com)
A Lexile measure is a valuable piece of information about either an individual's reading ability or the difficulty of a text, like a book or magazine article. The Lexile measure is shown as a number with an "L" after it — 880L is 880 Lexile.
A student gets his or her Lexile reader measure from a reading test or program. For example, if a student receives an 880L on her end-of-grade reading test, she is an 880 Lexile reader. Higher Lexile measures represent a higher level of reading ability. A Lexile reader measure can range from below 200L for beginning readers to above 1600L for advanced readers. Readers who score at or below 0L receive a BR for Beginning Reader.
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. A Lexile text measure is based on two strong predictors of how difficult a text is to comprehend: word frequency and sentence length. 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. 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 at or below 0L are reported as BR for Beginning Reader.
The idea behind The Lexile Framework for Reading is simple: if we know how well a student can read and how hard a specific book is to comprehend, we can predict how well that student will likely understand the book...
When you receive a Lexile measure, try not to focus on the exact number. Instead, consider a reading range around the number. A person's Lexile range, or reading comprehension "sweet spot," is from 100L below to 50L above his or her reported Lexile measure.
Some things to keep in mind:Lexile levels measure: Word Frequency and Sentence LengthLexile levels do not take into account Subject, Quality, Age Appropriateness and Reader's Interest

Information on Lexile to Grade comparison:"There is no direct correspondence between a specific Lexile measure and a specific grade level. Within any classroom or grade, there will be a range of readers and a range of reading materials. For example, in a fifth-grade classroom there will be some readers who are ahead of the typical reader (about 250L above) and some readers who are behind the typical reader (about 250L below). To say that some books are "just right" for fifth graders assumes that all fifth graders are reading at the same level. The Lexile®Framework for Reading is intended to match readers with texts at whatever level the reader is reading."
