Why can't Johnny sit still in his seat for more than a few minutes? Why does Sam engage in ritualistic behaviors and remain detached from reality and in his own world? How can I communicate with Jane when she repeats everything I ask her? These are some of many questions that will be answered in this handbook. These are the types of questions that are being asked by educators in schools across the country.

The problem is that there is lack of understanding of student disabilities and disorders. This lack of understanding exacerbates inappropriate behavior, student meltdowns, deficient classroom management, and below average learning and progress. The purpose of this book is to improve understanding of student disabilities and disorders. With better understanding, educators will be in a better position to use appropriate strategies and routines to control student behaviors and improve student learning and progress based on scientific evidence.
