The flight instructor reported that the student pilot flared high and the airplane bounced on touchdown. Subsequently, the airplane veered to the right during the landing roll and the flight instructor took the flight controls and added power to abort the landing, but the airplane continued off the runway to the right. The right elevator struck a taxiway sign during the runway excursion, which resulted in substantial damage to the elevator.

The flight instructor did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
