Narrative:

Departure called for a climb to 3000 ft after departure, but ATC amended the climb to 2000 ft. During the takeoff briefing, we briefed that the captain would fly and we would level at 2000 ft. After takeoff, the altitude alerter went off 1000 ft prior to our assigned altitude. Due to the high climb rate we passed through 2000 ft because the captain did not initiate the leveloff early enough. Our aircraft was extremely light and we also had a light fuel load. Another factor was the captain's low time in type. I don't believe he was expecting a climb rate over 6000 FPM. ATC did not comment on our altitude bust of 500 ft. We quickly recovered back down to our assigned altitude. This happened at the end of a long day of flying, we were on our 5TH leg of the day.
