Narrative:

Aircraft X was a departure who was climbing VFR and called for an IFR clearance in the air. Aircraft Y was level flight at 6;000 feet. I was training a developmental (trainee) at the time. The developmental gave aircraft X a squawk code and told him to maintain VFR aob 5;500 feet. The pilot read this back. The developmental then cleared aircraft X. I immediately noticed that he did not check ask the pilot if he could maintain his own terrain/obstruction avoidance. I prompted the trainee and he immediately corrected the clearance. The pilot was instructed eventually to turn 15 degrees left 'vectors for climb'. The pilot answered 'roger and I just want to verify you are keeping me at 5;000.' the trainee read back 'affirmative maintain 5;000 and turn 15 degrees left.' a couple minutes later the pilot climbed to 5;300 feet and the trainee verified his altimeter setting. After verification of correct altimeter setting the trainee told aircraft X that he was 300 feet high (now in conflict alert with aircraft Y). The pilot said 'affirmative I climbed because you cleared me as filed.' we read the brasher statement and informed management of the loss of separation.the first issue was the clearance below the minimum vectoring altitude. In this case my trainee has been training for quite a awhile and this was not a mistake he has made recently. It caught me off guard and I was not able to stop the clearance from being issued. I did not immediately and corrected the trainee however the clearance had already been issued. In the future I need to work on not being 'caught off guard' and ready to stop a clearance at any time.

Title: ZID Center Controller instructor reported the trainee issued an IFR clearance to an aircraft below the Minimum Vectoring Altitude. Subsequently the aircraft climbed above their assigned altitude in conflict with an overflight.
