Central to LevelUp Reader is an automatic system that recommends books to students at appropriate levels of understanding. It is based on the MetaMetrics® Lexile Framework for Reading, which determines both the reading difficulty of books and each child’s current reading level. Most early readers—or those who cannot read yet—are given a BR (beginning reader) prefix and assigned a numerical Lexile level after the intake assessment. As reading skills develop, readers might be assigned a 150L–350L Lexile measure or higher. As proficiency grows, readers can reach up to 1280L Lexile.

Once a student’s starting reading level is determined, first books are recommended. Titles are recommended in a variety of subject areas, which appear on their personalized bookshelf, in a default range 100L points below to 50L points above their Lexile number. (This range can be adjusted independently of a student’s Lexile measure if desired.) All of the high-quality digital books in the LevelUp Reader library are aligned to the same Lexile Framework. This means that the books recommended are not difficult to the point of frustration, but are in an appropriate range so your child can understand the text and be provided with just enough of a challenge to promote reading growth.

In simple terms, the Lexile framework ensures that books recommended by LevelUp Reader are just right—not too difficult, but not too easy. This assures that students are always presented with an individualized reading challenge.

LevelUp Reader provides Lexile measures throughout both the student and teacher interfaces.
