The Lexile Framework for Reading measures student ability and text complexity on the same scale. This means that students, books, and other reading materials have Lexile measures.  They help a reader choose a book or other reading material at an appropriate difficulty level when used together. The Lexile student measure can also be used to monitor a reader’s growth in reading ability over time and connect them to the reading demands of the real world.

To learn more, visit our pages for Educators and Parents.

The Quantile Framework for Mathematics provides teachers with a scientific way to measure a student’s ability to learn new math concepts and the difficulty of math skills. Each of these measures are on a single scale so that the skill demand and student ability can be matched for personalizing instruction for your students.

To learn more, visit our pages for Educators and Parents.

The Lexile and Quantile Frameworks are systems that measure student performance and material complexity on a single scale. Both are based on observed relationships between learners and materials, offering accurate measures from beginner to advanced levels. The scales are independent, meaning they can be used with various assessments and materials.

• Lexile Framework: Measures student reading ability and text complexity.
• Quantile Framework: Measures student math readiness and the difficulty of math skills and concepts.

These Frameworks provide insight into both student progress and material difficulty.

When a book is written for a specific use or style that may be of interest to end users, MetaMetrics provides codes to accompany the measures. 

For Lexile measures, the codes are:

• AD - Adult Directed: Better when read aloud to a student.
• HL - High-Low:  High-interest and age-appropriate content at a lower reading level.
• IG - Illustrated Guide: Nonfiction materials often used for reference.
• NC - Non-Conforming: For high-ability students who still need age-appropriate content.
• BR - Beginning Reader: For students with a Lexile measure below 0L. BR is the only Lexile code that applies to both readers and text. 
• GN - Graphic Novel: Graphic novels or comic books.
• NP - Non-Prose: Text with non-standard or absent punctuation (e.g. poetry or plays).

Visit our page Lexile Codes for Matching Readers to Books to learn more.

For Quantile measures, the codes are:

• EM - Emerging Mathematician: Measures below 0Q are reported as EM---Q (e.g., a Quantile measure of -120 is reported as EM120Q). This code is predominantly seen for material and student measures at the early grade levels.
• HMC - Higher Mathematical Content: Material designated as “HMC” is content for which we have QSCs but the QSCs have not yet been researched to identify their measures. These QSCs are currently in statistics and precalculus.
• NMQ - Not Measurable in Quantiles: Material designated as “NMQ” is content that is extensively diverse in QSCs or strands so it cannot be classified within the Quantile framework. Some examples are quizzes, tests, riddles, review sheets/activities, and process skills such as working backward, justifying, drawing pictures, etc.

We partner with the nation’s leading library automation services providers. All of these partners can provide Lexile measures and can integrate the measures into your school library catalog. Talk to your library automation representative about getting Lexile measures added to your catalog and search.

There are lots of ways to measure text. Readability formulas have been around for over a hundred years. What makes the Lexile Framework for Reading unique is that it measures both the reading material and the learner’s ability. The technical way of describing the Framework is as a “conjoint measurement model,” which is a technical way of saying the Lexile scale can be used to measure the difficulty of a book and the reading level of a learner. Because the Lexile Framework for Reading measures both text complexity and learner ability on a single scale, educators can match texts to students for targeted practice, progress monitoring, and projecting expected growth more easily.

To learn more, visit our pages for Educators and Parents.

A benefit of using both the Lexile Framework for Reading and the Quantile Framework for Mathematics is that they open up new possibilities for users. These metrics are used worldwide in assessments, learning platforms, and published materials. They help identify the reading and math skills needed for success in school, careers, and daily life.

The Lexile scale measures any type of prose text, while the Quantile scale measures math skills. Many organizations, educators, and departments of education use these frameworks to assess real-world materials, such as workplace documents, textbooks, and exams. This allows educators to compare a student’s abilities to the demands of real-world reading and math, making it easier to set and reach goals.

Sentence length is a powerful indicator of syntactic complexity. Longer sentences typically contain more clauses and, therefore, more information. Students who read a long sentence must retain information for an extended period before they arrive at the complete message. The student’s short-term memory is working to hold and then process all the information. Shorter sentences put less burden on short-term memory.

Vocabulary is an important indicator of the complexity of a text. Familiar or frequently used words are less challenging to a learner than rare or less frequently used words.

There are three likely reasons a book may display two different Lexile measures:

• Sometimes publishers submit books with the same title, but the contents may be slightly different depending on the edition. 
• In 2017 MetaMetrics updated the Lexile algorithm to better account for special text characteristics (i.e. decodability of words, sentence patterns, high-frequency words, repetition). This update allows for the precise assignment of Beginning Reader (BR) measures. However, some previously measured books’ Lexile measures also changed to reflect the enhanced algorithm. 
• There may be an error in the information management system. If that is the case, the Find a Book team will be notified and will correct the error.

See the Text Analyzer User Guide to learn details about what type of texts can be submitted to the analyzer and how to prepare your texts for analysis. 

Note: The Lexile Text Analyzer will not provide a certified Lexile measure text.

Yes, it means that the book will contain all five of the short vowels. There may not be equal percentages across all short vowels, but all short vowels will be represented at least once. Whenever you search by vowel sound in Find a Decodable Book, you can view the book details page to learn more about the categorization of the individual words in the book.

To learn more about word categorizations, see the Find A Decodable Book User Guide.

The Math Skills Database helps you unpack your state standards into Quantile Skills and Concepts. Enter the Quantile range of the students in your class to learn which of the QSCs are above, below, and within your students’ math readiness range. Use the Resource Centerto find free resources that are within the student’s Quantile range.

The Lexile & Quantile Career Databases are tools for identifying the reading and math abilities necessary for career preparedness. They contain Lexile and Quantile measures for more than 600 careers (to date) as well as important descriptive information, such as median pay, projected career growth, and education level required for each career. 

The databases are the result of years of research examining the text complexity of a variety of reading materials in various domains of the post-secondary experience. They provide the only metric available to compare and describe the reading and math demands of careers.

The national and regional career data used in the Lexile and Quantile Career Databases come from three sources:

• The O*NET Program is the nation's primary source of occupational information. O*NET information is used by millions of individuals every year, and the data have proven vital in helping people find the training and jobs they need.
• Bureau of Labor Statistics, a unit of the United States Department of Labor
• Projections Managing Partnerships, an integrated, nationwide program of state and local projections

To learn more about these organizations and how entry-level career demands are mapped to the Lexile and Quantile scales, visit the Lexile & Quantile Career Database User Guide.

Norms, like those presented on the Grade Level Charts, provide a measure of how students at a given percentile typically perform. Norms are not a judgment of what is good, bad, or acceptable, they simply indicate what is a typical performance at a given percentile.

Standards are performance targets set by a group or organization. A standard uses data to set goals and to determine when performance exceeds, meets, or misses expectations. In education, standards are typically set by states and each state has its own standards.

So, a student at the 50th percentile could be both at the midpoint of student national norms and “not meet grade-level performance standards” in their state.

To learn more about the differences between norms and standards, visit the Norms and Standards: How the Tilt-A-Whirl Can Help Explain Student Data blog post.

Probably! When developing the passages, we recorded the scope and sequences of 25 different reading programs, including core curricula, in use across the country. We then analyzed the order of the short vowels that appeared in each scope and sequence and designed stories to come up with the following instructional skills:

• short a
• short a, short i
• short a, short e
• short a, short o
• short a, short u
• all short vowels
• all short vowels + a blend or a digraph

Explore, save, and print Decodable Passages from the Resource Center.

The math resources in the Resource Center are the same as those in the Math Skills Database. They were added to both locations because we know that there are different ways that some might want to look for math resources.

The Math Skills Database allows for the ability to search for resources by a particular math standard and grade level while the Resource Center allows for the ability to search by title, type, and Quantile.

Sometimes, multiple tests taken within 30 days that report Lexile or Quantile measures show unexpectedly different results. You might wonder why this happens, which measure to use for instructional purposes, or how to explain it to parents. The Measures Manager tool helps educators determine a student’s optimal measure. The tool analyzes the test types, their purpose, and the student's grade level, along with the measures to provide the most accurate estimate of their current reading or mathematical ability.

Try the tool for yourself or learn more below.

Several factors can cause students to receive different scores on tests, including:

• Student factors: A student’s focus can be affected by fatigue, motivation, or outside stress. If they aren't fully focused, they may rush through the test, not read questions carefully, or miss details, affecting their performance.
• Test factors: Tests are designed for different purposes. For example, a progress-monitoring test gives different insights than a high-stakes, end-of-year test, which often motivates students more. Summative tests typically carry more weight and may impact grades or graduation.
• Administration factors: How and where the test is given also matters. Distractions like poor lighting, noise, or missing tools can affect performance. Proper test security is important—students accessing outside help or seeing test-related materials during the test can alter results.
• Combination of factors: Often, it’s a mix of these factors that leads to variations in scores. For example, students might be more motivated for a high-stakes test given under strict conditions compared to a lower-stakes one in a relaxed environment.

In summary, score variation is normal and expected, whether it's on the same test taken at different times or across different types of tests.

Educators can help diminish test score fluctuation when they: 

• Communicate upcoming assessment dates in advance with parents and caregivers.
• Encourage parents to help their child get a good night’s rest and a healthy breakfast before a test.
• Motivate students through praise and encouragement. Highly motivated students perform better and see less variation in their test scores. Studies show that students achieve at higher levels when they feel competent and see a direct link between their actions and an outcome.

Parents play an important role in motivating their children to succeed academically and, as an educator, you can provide parents with information to support students.  Be sure to communicate testing dates to parents in advance and provide the following tips for their child’s success:

• Help your child get a good night’s sleep before the test. 
• Make sure your child eats a healthy breakfast the morning before the test. 
• Talk to your child about the importance of doing their best on a test to show what they know and have learned.

To help parents better understand test results you can share the following guide with them:

• Interpreting Test Results Parent Explainer to help them understand why scores fluctuate and what they can do to help their child perform at their best on a test.
• Lexile & Quantile For Parents to provide an overview of the measures and what they can do with them.
