Narrative:

I was the radar controller at ind/hi. My airspace is 300-350. Rsh/shb/tth 75/34/35 were combined altitude 110-290; sectors were combined for training. Rsh handed an aircraft off to me leaving FL210 and transferred communications. The aircraft was climbing poorly to FL310. I called the d-side and requested control for direct cae. It was approved. I did this to avoid the inbound mdw/ord arrival traffic descending to FL300; 80 to 100 miles ahead. I called again and asked ensuring they would provide separation to the mdw/ord traffic by descending the mdw traffic; or if I should stop at FL290; they said they would separate. The trainee became over tasked and did not separate; started not taking hand offs; and I turned the aircraft 40 degrees to ensure separation. The trainee continued to hand aircraft off well below the limits of their airspace. I received several hand offs on aircraft 8;000-10;000 ft below my bottom limits. These aircraft became a conflict with other aircraft below my altitude limits. I turned several aircraft below my limits to ensure separation within the limits of the rsh sector. Several times before the incident I advised the supervisor to 'split the sector'; he did not. The student asked for a tracker. I believe both the student and the instructor were over tasked. There was a heated discussion between the d-side and the ojti during the event due to the lack of input from the ojti to student. After the session the supervisor agreed he 'should have split' the sector. Dysim is the correct venue to 'push' the trainee; not with live traffic. The trainee was not prepared to work the volume exposed to and this created an unsafe environment; also placing an undue burden on the surrounding sectors.

Title: ZID Controller witnessed an unsafe condition when adjacent sectors were combined for training and handoffs were not completed as required; the reporter stating the combined sectors should have been split long before the event.
