Accelerated Reader is basically a reading incentive program. Thousands upon thousands of books have had AR tests created for them. These multiple choice tests determine whether or not a student really read a book. Each AR book is assigned a level and a point value. For example, Jeff Kinney's very popular Diary of a Wimpy Kid has an AR level of 5.2 and is worth 3 points. A general rule of thumb for AR levels is that they correspond with grade levels, however many students read above or below their actual grade level. Other examples include Kevin Henkes' Kitten's First Full Moon. This fairly simple picture book has a 2.3 reading level and is worth 0.5 of a point. The fourth installment of J.K. Rowling's Harry Potter series, Harry Potter and the Goblet of Fire, is 6.8 level and is worth a whopping 32 points.
