Dr. Glasser trained therapists and others mainly through the William Glasser Institute, a nonprofit organization he founded outside Chicago. In his book “Choice Theory,” he summarized its strategy as helping patients and schoolchildren to shift their view of reality fundamentally — from one where behavior is controlled externally by coercion, to one where individuals control their own behavior in an atmosphere of “love, friendship, negotiation and trust.”

Teachers, along with marriage therapists and drug counselors, have been enthusiastic proponents of Dr. Glasser’s approach. Several thousand teachers have received training from the institute, according to a spokesman. And about 20 small or medium-size school districts have adopted his theories, receiving the institute’s imprimatur as “Glasser Quality Schools.”
