"This report has reviewed the method of AIT most commonly used in the U.S. and offered as treatment for a variety of communication, behavioral, emotional, and learning disorders. Despite approximately one decade of practice in this country, this method has not met scientific standards for efficacy and safety that would justify its inclusion as a mainstream treatment for these disorders. - See more at: http://www.asha.org/policy/TR2004-00260/#sthash.TFZHUV42.dpuf"
