Diane Brooks is Melody's middle school principal in the book "Out of My Mind". She is described as a stern and no-nonsense administrator who is more concerned with enforcing the school rules than understanding Melody's unique situation. She is initially unsympathetic to Melody's need for a communication device but later comes around when Melody's story is widely publicized in the media. Overall, Diane Brooks is portrayed as a strict but ultimately reasonable authority figure in the book.
