Aircraft X was a student pilot on a practice ILS approach at TISX. The pilot was requesting one ILS approach at with a missed approach. I had coordinated with tower the missed approach instructions heading 045 as per the letter of agreement for props and turboprops departing to the northwest and climbing to 6000 feet. The tower controller acknowledged this instruction. I cleared Aircraft X for the ILS approach; gave the tower the position report (12 miles west) and switched Aircraft X to tower. I was expecting the aircraft to continue on a low approach to the departure end before turning to a heading of 045 when all of the sudden the aircraft is on the approach end and calls me back that is climbing out of 1000 feet to 6000 feet on the missed approach heading 045. The MVA (Minimum Vectoring Altitude) in that area is 2400 feet due to mountainous terrain on the north side of the airport. I asked the pilot if he could maintain his own terrain and obstruction clearance up to 2400 feet and the pilot stated that on a heading 050 he could avoid terrain. I then stated to the pilot to maintain his own terrain and obstruction clearance and leaving 2400 feet fly heading 300. Aircraft X acknowledged and when he left 2400 feet; he joined his route without any problem.It was my understanding that the tower controller at TISX has to be aware that by turning Aircraft X on the approach end instead of the departure end is going to put the aircraft in the proximity of terrain; especially a slow climbing and slow moving aircraft. I do not know if there was expectation bias on my part regarding what I expected from the tower controller and missed approach instructions regarding practice approaches. In the future I would be more specific with the tower regarding missed approach instructions when working practice approaches. I also should have issued Aircraft X a safety alert (low altitude alert).
ZSU Controller reported an aircraft initiated their go-around instructions from the approach end of the runway at TISX instead of the departure end which placed the aircraft below the MVA.
