The Lexile® Framework for Reading

Overview

The Lexile® Framework for Reading is a scientific approach to reading and text measurement. There are two Lexile® measures: the Lexile reader measure and the Lexile text measure. A Lexile reader measure represents a student's reading ability on the Lexile scale. A Lexile text measure represents a text's difficulty level on the Lexile scale. When used together, they can help a reader choose a book or other reading material that is at an appropriate difficulty level. The Lexile reader measure can also be used to monitor a reader's growth in reading ability over time.

A higher Lexile reader measure represents a higher level of reading ability on the Lexile scale. A Lexile reader measure is obtained by having the reader take a test of reading comprehension. There are more than 45 assessments that can report Lexile reader measures, including the New Mexico Standards-Based Assessment (SBA) for grades 3-8. The Lexile measure for 3rd-8th graders appear on the EOG test score report. A student's Lexile range spans from 100L below to 50L above his or her reported Lexile measure.

A Lexile text measure, like a Lexile reader measure, is reported on the same Lexile scale. The Lexile scale spans from below 0L for beginning reader text to above 1600L for more advanced text. A text receives a Lexile measure when MetaMetrics analyzes the complete text using propriety software that evaluates its various dimensions.

Matching Readers with Text

A useful feature of Lexile reader and text measures is that they can be used together to predict how well a reader will likely comprehend a text at a specific Lexile level. For example, if a reader has a Lexile measure of 1000L, he will be forecasted to comprehend approximately 75 percent of a book with the same Lexile measure (1000L). The 75-percent comprehension rate is called "targeted" reading. This rate is based on independent reading. If the reader receives assistance, the comprehension rate will increase. The target reading rate is the point at which a reader will comprehend enough to understand the text, but will also face some reading challenge. At this challenge point, a reader is not bored by text that is too easy, but also does not experience too much difficulty in understanding. The result is a rewarding reading experience.

Recognized as the standard for matching readers with texts, students can find targeted readings from more than 100 million articles, books and websites that have been measured. The New Mexico state online database EL Portal offers a search feature that enables users to search magazines, journal, newspaper articles, and e-books by Lexile measure. Many popular catalog automation products and content aggregator products provide Lexile text measures for their materials. For a complete list of resources that report out Lexile measures, visit Lexile.com. The "Find a Book, New Mexico" tool also helps a student find books that match their Lexile measure and interests.
