Hello, Teacher! Want AR levels and classroom reading habits in one place? Bookroo Classroom helps teachers turn book data into action. Check out Bookroo Classroom.
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.
Search for a book, enter a quiz score, and estimate how many AR points that result would earn.
