MAP Assessments Continue Lexile Reporting

NWEA’s Measures of Academic Progress® (MAP®) assessments are used by nearly 5,000 U.S. school districts and educational agencies worldwide. And each of them will be glad to know that the tests will continue to report Lexile® ranges.

Today, Lexile-developer MetaMetrics® and NWEA announced that they have extended their partnership that dates back to 1999. Since then, MAP reports have included a reading range score that correlates a student’s MAP test score with a Lexile range. The Lexile range is used to provide the student with a pre-developed booklist intended to support growth by providing the right level of challenge for his or her reading ability. And, for those who are familiar with our free “Find a Book” search tool, the student’s Lexile range can also be used to build a custom reading list based on his or her ability and interests, and then locate the selections at a local public library.

When asked about the value of Lexile ranges from the MAP assessments, NWEA President and CEO Matt Chapman noted, “… we are committed to providing not only data, but meaningful instructional tools to appropriately help kids learn and teachers be more effective—Lexile measures help us towards that goal.” 

MetaMetrics President and co-founder Malbert Smith III added, “We are pleased … to maintain the continuity of Lexile data that so many educators trust to guide their classroom instruction. More than ever, educators must continually assess how much reading growth is required for students to achieve state and national proficiency standards, and as they prepare for the reading demands of their college and career goals.”

MAP adaptive assessments provide valuable information about students’ learning level and growth, as well as their progress toward state and national standards. They are computer-adaptive and adjust with each item, giving a precise and accurate measure of student learning and growth, based on NWEA’s RIT scores. For more information, visit
