Human Factors
Touched down for touch and go; was too far left of center line to take off. Corrected with right rudder to get back onto center line; put in full power and was pulled to the left of center line. Over corrected with right rudder and again with left rudder; with full power in; was taken off of [the runway] onto the grass after [the crossing runway] intersection and into the grass. Regained aircraft control and stopped on taxiway. Shut down aircraft on taxiway after tower approval and did a walkaround to determine if the aircraft was damaged. After no visual damage; the aircraft was restarted and went through a typical run up. No abnormalities were noticed and the aircraft was taxied to the hold short line of [the runway] and proceeded to do a normal takeoff.
Student arrived at airport after cross country flight for training purposes; I had inquired with the student how the flight went and the student told me that the flight did not go well and that he had a runway excursion. When I had further inquired what had happened student told me that when flying into [the airport] he had been doing touch and goes which were not authorized as per our training programs Pilot Training Operations Manual for solo flight. When he had landed after his second lap in the traffic pattern he had removed flaps and added full power after landing off centerline. He said the aircraft had then started to turn and he then proceeded to over correct with rudder which led to then veering of the runway into the grass followed by entering a taxiway. Tower then proceeded to call out assistance to make sure the student and aircraft were ok. After an inspection the student started up the aircraft and got cleared for an intersection departure where he terminated his flight.
C172 student pilot and instructor reported a runway excursion while the student was doing solo touch and goes; which were not approved under solo flight conditions.
