This book is on a DRA reading level of 50, and can be read to audiences of third grade to eighth grade. I would use this in an older grade classroom because it deals with more mature topics, such as loss. It could be read in a class if one of your students is dealing with a loss, because sometimes it helps to hear about someone else who has dealt with loss and grief before. It would give them something to relate to. Aside from the grief in the story, there is a lot of adventure that gives the story an upbeat plot. I mean the story is about two unlikely friends that become best friends and adventure to their imaginary world of Terabithia. It is a wonderful story!
