Lexile® measures are provided in Imagine Language & Literacy (IL&L) only for those students who take the Reading Level Assessment. This assessment must be enabled by an administrator in order for students to take it.
The MetaMetrics® company developed the Lexile® Framework for Reading, which measures the following two items on the same scale:
- a student's reading ability
- the text complexity of reading materials
The framework then reports these characteristics as a Lexile measure – a number followed by an “L.”
MetaMetrics measured the following expected growth of general education students for each grade level:
|Expected increase in Lexile Measure from BOY to EOY
Across all grade levels, Imagine Learning observed that IL&L students (both ELL students and general education students combined) demonstrated an average growth of 120L per year, with more gains for students who used the program at least 20 hours during the academic year.
Results vary by grade level, with lower grades showing a higher increase. Numbers may also vary by student population. For example, schools with a high percentage of emergent multilingual learners may observe different gains than schools with other sociodemographic characteristics.

After students complete the Reading Level assessment, their results can be found in the Growth section of the educator portal. To view your students' Lexile growth, follow the steps in this article.
