Lexile Text Measures

Overview and Introduction

The Lexile Framework for Reading, developed by MetaMetrics, Inc., is a scientific, proven approach to reading and text measurement. Recognized as the most accurate way to match readers with text, there are currently Lexile measures for more than 100,000 books, 80 million articles, and 60,000 Web sites. More than 20 million students received a Lexile measure during the 2005-2006 school year. The Lexile measure provides educators with a powerful tool to forecast expected comprehension rates and match readers with text.

What is the Lexile Framework for Reading?

The Lexile Framework for Reading consists of two main components: a Lexile measure and the Lexile scale. A Lexile measure is the numeric representation of a reader's ability or a text's difficulty, both followed by an "L" (for Lexile). The Lexile scale is a developmental scale for reading that ranges from below 0L for emerging readers and beginning texts to above 1700L for advanced readers and texts. Values at or below 0L are reported as Beginning Reader (BR).

A Lexile text measure is obtained through analyzing the text difficulty of a piece of text. The Lexile Analyzer, a software program specially designed to evaluate the reading demand of text, analyzes the text's semantic and syntactic characteristics and assigns it a Lexile measure. A multi-step process is required to prepare the text before it is submitted to the Lexile Analyzer for a measure.

Extensive information about the development of the Lexile Framework for Reading can be found in the Researchers section of the Lexile website. In particular, a white paper entitled The Lexile Framework as an Approach for Reading Measurement and Success provides detailed descriptions of each component of the Lexile Framework for Reading.
