Some tools for parents to determine the reading level of books include Scholastic’s Book Wizard and Level It Books. Other tools designed for teachers to use in the classroom include the Lexile Framework for Reading, the Developmental Reading Assessment and the Qualitative Reading Inventory.
Book Wizard is a free online tool that lets users find a book’s reading level on several different scales at once, including the Lexile, Developmental Reading Assessment, Guided Reading and Grade Level Equivalent scales. Type in a book’s title or using the mobile app to scan its International Standard Book Number returns information on the book’s reading level, interest level and genre, as well as other free resources. Similar to Book Wizard, Level It Books scans a book's ISBN and returns its classification on the GLE, Lexile, GR and DRA scales. The mobile apps are available for both Android and iOS platforms.
For a better understanding of how the ratings scales work, parents can also learn to use classroom instruments to level books. For instance, MetaMetrics, which developed the Lexile scale, offers workshops to teach parents how the scale was developed and how it assesses reading levels. Many book vendors offer the Qualitative Reading Inventory in book form, and Pearson and other vendors offer complete DRA2 kits.
