Interpret Reading Results

A Lexile is a unit that measures the amount of challenge presented by a passage based on vocabulary and sentence complexity

A Lexile measure represents a location on the Lexile scale where a reader can expect a 75% comprehension rate - difficult enough to be challenging without undue frustration and to encourage reading progress.

What is a Lexile?

Typical Lexile Ranges for Grade

Grade Lexile Range1 BR to 300L2 140L - 500L3 330L - 700L4 445L - 810L5 565L - 910L6 665L - 1000L7 735L - 1065L8 805L - 1100L9 855L - 1165L10 905L - 1195L

11 and 12 940L - 1210L*K5 students are typically at the beginning reader stage and usually score a Lexile of BR. Reporting Lexiles for K5 students isn't required. It is recommended to report out a Lexile for a K5 student that is above the typical Lexile for K5 students.
