Report will Air on "World News with Diane Sawyer" and "Nightline" on Thursday, November 29

Thousands of American school children who suffer with autism or have other behavioral issues have reportedly been injured and dozens have died after poorly trained teachers and school aides tried to subdue them, a major ABC News investigation has found. It is a troubling trend in the use of unduly harsh methods to restrain students who misbehave. The report from ABC News Chief Investigative Correspondent Brian Ross airs Thursday, November 29 on " World News with Diane Sawyer" and " Nightline." In addition, it will be featured on ABCNews.com, Yahoo!, ABC News Radio and ABC's local affiliates.

Ross interviewed a number of people at the center of this shocking investigation, including victims' mothers, children with compelling and chilling firsthand accounts, Congressman George Miller who is calling for national legislation restricting how and when restraints can be used on school children, and the Head of the School Superintendents Association, who opposes the legislation and says schools need the ability to use a variety of techniques to restrain children who poses a risk of harm to themselves or others.
