Primary problem: Procedure

Narrative: I was providing OJT Instruction. Aircraft X reported a planned missed approach. The trainee cleared Aircraft X to 'turn direct' or 'cleared direct' to a different IAF before Radar identifying or climbing Aircraft X to an altitude above the Minimum IFR Altitude (MIA). Aircraft X was below the MIA/MVA when direct clearance was issued.Missed approach procedures may or may not be thoroughly taught/discussed in the training department. That RADAR service has been terminated; that RADAR identification and Mode-C verification; and altitude assignment will need to be issued/verified.


Second narrative: I was training on the sector. I had received the briefing and started working the sector. In the briefing I was told that the Aircraft X was going to be doing multiple approaches to both runways. I cleared Aircraft X for the approach that he had requested. After his approach; he contacted me stating that he was climbing and I heard something to the effect of direct ZZZZZ. I became nervous as I pulled up the Minimum IFR Altitudes and saw the aircraft direct to an 11000 foot MVA area and he was at 9300 feet. Without giving him a climb higher above the MIA I reacted by turning the aircraft left direct ZZZZZ1 as an attempt to turn him away from the higher terrain. ZZZZZ1 is another fix for the approach that the aircraft was requesting. Immediately after I took the action I realized what I had done; but I had already turned the aircraft. After which I gave a climb to that aircraft to get him above the MIA. After being involved in this incident; I have gone over this over and over to myself. My trainer has also discussed in depth as to what I did; and what I should have done. I have realized that my mistake was caused by unclear communication between myself and the pilot. It was also compounded with the amount of traffic and the complexity for me of having one aircraft attempting multiple approaches at one airport. I understand what my actions have led to; and I will not clear an aircraft below the MIA again. In order to prevent this occurrence my trainer and I have discussed how I should've handled the situation; by being clear as to what is being done and requested; and before clearing an aircraft it must be above the MIA.


Synopsis: A trainee controller cleared an aircraft conducting a missed approach to a fix while it was still below the Minimum IFR Altitude/MVA and prior to Radar identifying and verifying Mode C of the aircraft.
