Each year, hundreds of thousands of students in grades 1-3 receive DIBELS ORF scores. By converting scores from DIBELS 6th Edition into corresponding Lexile® measures, educators and parents can match young readers with books and other materials that are targeted to their individual abilities and interests.
To get started, download one of the conversion tables below. Once you know a student's Lexile measure, you can use Find a Book to search the Lexile Book Database for books within the student's Lexile range—about 50L above and 100L below his or her Lexile measure. By reading "targeted" books within this Lexile range, the student should be able to comprehend enough of the text to make sense of it, while still being challenged enough to maintain interest and learning.

Interpretations and Uses of Lexile Measures
(Excerpted from Linking DIBELS Oral Reading Fluency with The Lexile Framework for Reading.)
The Lexile Framework for Reading provides teachers and educators with tools to help them link assessment results with subsequent instruction. When a reader takes an assessment that is linked with the Lexile Framework, his or her results are reported as a Lexile measure. This means, for example, that a student whose reading ability has been measured at 500L is expected to read with 75-percent comprehension a book that also is measured at 500L. When the reader and text are matched (same Lexile measures), the reader is "targeted." A targeted reader reports confidence, competence and control over the text.
When reading a book within his or her Lexile range (50L above his or her Lexile measure to 100L below), the reader should comprehend enough of the text to make sense of it, while still being challenged enough to maintain interest and learning. When a text measure is 250L above the reader's measure, comprehension is predicted to drop to 50 percent and the reader will likely experience frustration and inadequacy. Conversely, when a text measure is 250L below the reader's measure, comprehension is predicted to go up to 90 percent and the reader is expected to experience control and fluency.
Using The Lexile Framework for Reading to Select Books
Teachers, parents and students can use the tools powered by the Lexile Framework to plan instruction (e.g., the Find a Book search). When teachers provide parents and students with lists of titles that match the students' Lexile measures, they can then work together to choose appropriate titles that also match the students' interest and background knowledge. The Lexile Framework does not prescribe a reading program, but it gives educators more control over the variables involved when they design reading instruction. The Lexile Framework yields multiple opportunities for use in a variety of instructional activities. After becoming familiar with the Lexile Framework, teachers are likely to think of a variety of additional creative ways to use this tool to match students with books that students find challenging, but not frustrating.
Remember, there are many factors that affect the relationship between a reader and a book. These factors include text content, age of the reader, interests of the reader, suitability of the text, and text difficulty. The Lexile measure of a text, a measure of text difficulty, is a good starting point in the selection process, but other factors also must be considered. The Lexile measure should never be the only piece of information used when selecting a text for a reader.
Communicate With Parents Meaningfully to Include Them in the Educational Process
Teachers can make statements to parents such as, "Your child will be able to read with at least 75-percent comprehension these kinds of materials which are at the next grade level." Or, "Your child will need to be able to increase his/her Lexile measure by 400L-500L in the next few years to be prepared for college reading demands. Here is a list of appropriate titles your child can choose from for reading this summer."
Improve Students' Reading Fluency
Educational researchers have found that students who spend a minimum of three hours a week reading at their own level for their own purposes develop reading fluency that leads to improved mastery. Not surprisingly, researchers also have found that students who read age-appropriate materials with a high level of comprehension also learn to enjoy reading.
Apply Lexile Measures Across the Curriculum
Over 150 publishers have Lexile measures for their trade books and textbooks, enabling educators to link all of the different components of the curriculum to more effectively target instruction. With a student's Lexile measure, teachers can connect him or her with tens of thousands of books and tens of thousands of newspaper and magazine articles (through periodical databases) that also have Lexile measures.
