Lexile® & Quantile® Measures
The California Department of Education (CDE) has partnered with MetaMetrics® to provide additional measures of students' abilities in reading and mathematics. Lexile measures indicate students' reading abilities and Quantile measures indicate students' readiness for instruction in mathematics. Access the Introducing Lexile and Quantile Measures web document for additional information about these measures.
The Lexile Framework for Reading and Quantile Framework for Mathematics have been linked to the California Assessment of Student Performance and Progress (CAASPP) Smarter Balanced English language arts/literacy (ELA) and mathematics assessments. Students who complete these assessments will receive a separate Lexile and Quantile Measures Report. Access the Sample Lexile and Quantile Measures Report for an overview of sample measures and suggested resources.
A Lexile measure indicates the difficulty of materials a student can read and understand. It is based on a student's Smarter Balanced ELA score. With the help of Lexile measures, parents and educators can find reading materials at the appropriate difficulty level for students and monitor their growth in reading over time.
A Quantile measure shows what mathematical skills a student has mastered and which skills they need additional instruction in. It is based on a student's Smarter Balanced mathematics score. With the help of Quantile measures, parents and educators can identify the mathematical skills needed to support students' learning and monitor their growth in mathematics over time.
The following deliverables have been developed to support the introduction of Lexile and Quantile measures and the Hub to parents/guardians.
- Introducing Lexile and Quantile Measures—An overview of Lexile and Quantile measures and an introduction to the Lexile & Quantile Hub. This document is intended for local educational agencies to use in their outreach materials to maintain consistent messaging about Lexile and Quantile measures and available resources.
- Lexile and Quantile Measures Parent Notification Letter Template—Customizable letter for parents/guardians about Lexile and Quantile measures that includes information about Lexile and Quantile Measures Reports. This letter is available in the following languages:
- Lexile and Quantile Measures Parent Notification Letter Template in English
- Lexile and Quantile Measures Parent Notification Letter Template in Spanish
- Lexile and Quantile Measures Parent Notification Letter Template in Vietnamese
- Lexile and Quantile Measures Parent Notification Letter Template in Traditional Chinese
- Lexile and Quantile Measures Parent Notification Letter Template in Filipino
- Quick Reference Guide—How to Self-Register for the Lexile & Quantile Hub—Step-by-step instructions for accessing the Hub and completing the self-registration process.
Lexile and Quantile measures are reported on a separate Lexile and Quantile Measures Report. Distribution of the Lexile and Quantile Measures Reports is optional. If a school or local educational agency chooses to distribute these reports through their student information system (SIS) or parent portal, they should confirm with their SIS vendor that they have met the most recent Application Programming Interface Specifications for reporting.
Coordinators can access the Lexile and Quantile Measures Reports in the Test Operations Management System (TOMS) using the following methods:
- Similar to other CAASPP Student Score Reports, the Lexile and Quantile Measures Reports are available as PDF files. Coordinators can access these files by navigating to the [Reports] tab and selecting “CAASPP Student Score Reports PDFs.” Then select “Lexile/Quantile” from the Assessments drop-down menu.
- Additionally, the Lexile and Quantile measures are included in the “CAASPP Student Score Data File.”
Lexile & Quantile Hub
The Lexile & Quantile Hub contains instructional planning resources for educators and a variety of tools that support the monitoring of student growth in reading and mathematics toward goals of college and career readiness. Parents/guardians, educators, and students can access a wealth of free, web-based tools to help find appropriately challenging learning materials. For additional information about the Hub, please visit the CAASPP Lexile & Quantile Hub web page.
