Lexile Grade Level Charts
What are Lexile Student Measures by Grade?
Lexile norms describe how students across the U.S. perform on reading assessments that have been linked to the Lexile Framework. They are based on a large, national sample of approximately 37 million students from 2021 - 2025. Results are expressed as percentiles, showing where a student stands compared to peers nationwide.

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”.
