"For nearly thirty years, Teacher Effectiveness Training, or the T.E.T. book, based on Dr. Thomas Gordon's groundbreaking program, has taught hundreds of thousands of teachers around the world the skills they need to deal with the inevitable student discipline problems effectively and humanely." "Now revised and updated, T.E.T. can mean the difference between an unproductive, disruptive classroom and a cooperative, productive environment in which students flourish and teachers feel rewarded."--BOOK JACKET.
