Narrative:

A probationary pilot was about to level off at FL350. At FL348, he put his hand on the autoplt. I thought he was cutting rate of climb. We were climbing at 500 FPM. I picked up the flight plan to enter top of climb fuel and time. I glanced at altitude and we were at FL352. I took control and leveled plane with autoplt, but climb rate continued. I disconnected autoplt and leveled off at FL353. I had to nose the plane over, but I did not want to risk injury to the flight attendants. I just did not ensure the other pilot leveled off at FL350. Corrective action: ensure plane and pilot level the plane or turn to heading or whatever before I tackle any extraneous duty.
