Lexile levels by grade are a set of standards used to measure the readability of text. They are assigned to books, articles, and other types of written material and help educators and parents determine the appropriate reading level for students.
Lexile levels are beneficial because they provide a common measure of readability across different types of text. This makes it easier to compare the difficulty of different materials and to track students’ progress over time. Lexile levels were developed by MetaMetrics, a company that specializes in educational assessment. The first version of the Lexile Framework was released in 1996.
