How to use this tool

If your school uses Accelerated Reader, three numbers decide whether a book counts: the AR book level, its point value, and the quiz number a student needs to log the test. This lookup surfaces all three, plus the interest level, for the AR-quizzed books in Bookroo's catalog.

Not every book has an AR quiz. When a title has no quiz on record, the tool says so directly — and can show an estimated ATOS-scale difficulty from the book's Lexile measure, clearly marked as an estimate rather than an official AR level.
