How do you find out what books have taken an Accelerated Reader test on?

There's no central, publicly accessible database listing every book ever tested with Accelerated Reader (AR). The AR Quiz database is proprietary to Renaissance Learning, the company that produces AR.

To find out if a specific book has an AR quiz:

* Use the Renaissance Learning website: Their website (typically renaissance.com) usually has a search function where you can enter the book's title and author. This is the most reliable method. You may need to be logged in with school credentials for full access.

* Check your school's library system: If you're a student, your school's library catalog or online system may indicate which books have AR quizzes associated with them.

* Ask your librarian or teacher: They will have access to the school's AR system and can tell you if a specific book has a quiz available.

There's no way to comprehensively search for *all* books with AR quizzes without access to Renaissance Learning's internal database.
