Narrative:

I was letting copilot fly in preparation for a part 135 check ride. We were cleared from 3000 ft to 'climb, maintain 6000 ft.' the copilot was hesitant at leveloff and the aircraft continued to climb to 6400 ft and was brought back to 6000 ft. We were then cleared to 9000 ft, there was no conflict. I feel this was a result of inexperience on the copilot in flying high performance aircraft. However, I was PIC and should have reacted sooner.
