Human Factors
I was working the Ground Control position. Local Control was busy working aircraft within the Delta airspace. I had given taxi instructions to Aircraft X. The pilot had trouble acknowledging the clearance and sounded as if he was a student pilot. I relayed instructions to the pilot again to taxi to the runway to which he acknowledged the instructions. He advised me on frequency he was 'ready to go.' I instructed Aircraft X to contact Tower as I saw the aircraft holding short of the runway. Some coordination occurred between our Radar Controller and Local Control and a crop duster had called on Local Control frequency. As I took care of an IFR clearance and taxi instruction; I look up and see Aircraft Y on short final and an aircraft on the runway. The pilot of Aircraft Y is keying up on frequency saying 'What is that aircraft doing on the runway?' As the Controller in Charge in the Tower; I instructed the Local Controller to have Aircraft Y to go around. The pilot sidestepped to the side of the runway and went around. The Local Controller reached out to Aircraft X on frequency to turn left and exit the runway immediately. The pilot was later given the Brasher Statement and taxied back to the runway for departure. The pilot of Aircraft X never called for takeoff clearance and taxied onto the runway without any ATC instruction. The pilot attempted to takeoff without an ATC clearance. Had it not been for the swift collective action between ATC and pilots to initiate a go around; the aircraft may have collided.The aircraft came from a flight school that has had multiple issues with Air Traffic Control instructions at this facility in the past. The students of the flight school seem not proficient with Air Traffic Control procedures at controlled airports. Each time; the aircraft in question has either announced every single leg of the traffic pattern to the Control Tower acted like the airport was un-controlled. Additional training for the pilot of Aircraft X for operations at controlled airports and education about runway incursions.

Tower controllers reported an aircraft entered the runway without a clearance to takeoff with another aircraft on short final.
