Lexile Grade Level Charts
What are Lexile Student Measures by Grade?
A research study was conducted to describe Lexile ranges for each grade. Data for these national student norms came from a sample of over 3 million students across the United States and the Virgin Islands who were administered tests that reported Lexile measures from 2010 to 2019.
The Difference Between Student Norms and Performance Standards
Percentiles from national student norms describe how a student performed compared to all of the students measured. Performance standards are set by states and assessment developers. Labels such as “basic” or “proficient” are often applied to each standard. So, a student at the 50th percentile could be both at the mid-point of student norms and “not meet grade-level performance standards”.
