Piano teacher Christopher Lorge admitted tossing the paperback in February because the student was talking on a phone and wearing earphones.
The district suspended Lorge and started proceedings to terminate him.
But The Press of Atlantic City reports a state Education Department arbitrator found while the teacher displayed a "serious lack of judgment," he showed remorse and had worked 10 years without disciplinary action. The arbitrator declined to fire him.
