The Lexile Framework is a scientific approach
to reading measurement that matches readers to
text. The Lexile Framework measures both reader
ability and text difficulty on the same scale,
called the Lexile scale.
3
What is a Lexile?
A Lexile is a unit for measuring text
difficulty. The word Lexile is a blend of the
root word Lex, which refers to words, and
echoes the word percentile, a comparative unit
of measure. The Lexile Framework is a system of
measurement that quickly calibrates the
difficulty of most any textual material with a
high degree of accuracy.

The Lexile Framework Variables
Syntactic Complexity

• the number of words per sentence
• longer sentences are more complex and
  require more short term memory to process
• Semantic Difficulty
• the frequency of the words in a corpus of
  written text
• corpus has over 500-million words

Syntactic Complexity

• The best predictor of the difficulty of a
  sentence
• is its length.
• Longer sentences are likely to contain more
  clauses, and therefore to communicate not only
  more information and ideas but an
  interrelationship between them.
• Longer sentences require the reader to retain
  more in short-term memory in order to negotiate
  meaning.

7
Semantic Difficulty

• The difficulty of words is a continuum based on
  exposure.
• Knowing the frequency of words provides the the
  best means of inferring whether a word will
• become a part of an individuals vocabulary.

8

• Background
• Based on analysis of entire text.
• Created by a team of experts in the fields of
• measurement, testing and reading.
• Adopted by National Center for Education
• Statistics (NCES) as its measure of text
  difficulty.

Lexile Measures

• SRI Test results are reported in Lexiles
• The Lexile Number indicates 75 comprehension
• Books have Lexile Measures
• Match students and books, and plan instruction
  with
• Lexile Ranges

Use Lexiles To

• To promote reading progress
• To assign the right level of reading materials
  in
• all curricular areas
• As a flexible part of any reading program
• Connect students to tens of thousands of books
• Connect students to tens of millions of articles

The Lexile Map

• An educational tool that links text and readers
  under a common metric, Lexiles
• Characterizes reader with a measure and text with
  a measure
• Allows educators to forecast the level of
  comprehension a reader is expected to experience
  with a particular text

Classroom Uses

• Develop individualized reading lists
• Enhance thematic teaching
• Use as a tool for sequencing materials
• Develop a take home reading folder
• Adjust level of reading for special circumstances
• Assist in informed choice making for students

14
Lexile Facts

• Over 450 book publishers have titles with Lexile
  measures
• Nearly 50,000 books to search at www.lexile.com
• Over 70 million Lexiled articles through
  database-services partners

The Lexile Calculator

• Forecasted Comprehension
• The relationship between a reader and a text.
• How well the reader will comprehend the
  material in the text.
• Can perform the following calculations
• The rate at which a student is expected to
  comprehend of the text.
• The reading ability a reader is expected to need
  in order to comprehend the text at a specific
  level.

Lexiles give educators the confidence to choose
materials that will improve student reading
skills across the curriculum and at home.
