The Lexile® Framework for Reading


The Lexile® Framework for Reading
Oklahoma State Department of Education | (405) 521-3301

Notice: The Oklahoma Department of Education does not endorse or recommend reading material for its schools. Curriculum decisions are made at the district/local level in Oklahoma. Reading material for students should always be previewed by parents or educators.

The Oklahoma School Testing Program (OSTP), grades 3-8, has been linked with The Lexile® Framework for Reading. Students taking the end of grade English Language Arts (ELA) assessment will receive a Lexile measure on the individual student score report.

What is a Lexile measure?


The Lexile scale is like a thermometer that can help you measure a text's complexity AND your reader's ability. By knowing your child's Lexile measure and the Lexile measure of a text, you can find a good match for your child when selecting a specific book, magazine article or other reading materials. Remember, a good match will help increase your child's reading growth.

The Lexile measure is shown as a number with an "L" after it — 880L is 880 Lexile. For example, if a student receives an 880L on his or her end-of-grade reading test, he or she is an 880 Lexile reader. Higher Lexile measures represent a higher level of reading ability. A Lexile reader measure can range from below 200L for early readers to above 1600L for advanced readers.

A Lexile text measure, like a Lexile reader measure, is reported on the same Lexile scale. The lower a book’s Lexile measure, the easier it will be to comprehend. For example, a text with a Lexile measure of 850L will most likely be easier for a reader to comprehend than a text at 950L.

A very useful feature of Lexile reader and text measures is that they can be used together to predict how well a reader will likely comprehend a text at a specific Lexile level. For example, if a reader has a Lexile measure of 1000L, he will be forecasted to comprehend approximately 75 percent of a book with the same Lexile measure (1000L). The 75-percent comprehension rate is called “targeted” reading.

The Oklahoma State Department of Education wants to provide opportunities for all students to become good readers. After all, reading is an essential skill and one that is highly predictive of a student’s future success in school and on the job. In Oklahoma, we want to encourage reading year-round.

Linking assessment with reading instruction

When used together, Lexile reader measures and Lexile text measures enable educators, parents and students to select books and other targeted reading materials that meet and challenge a reader's unique abilities and interests.
