[We] departed Runway 24 at TEB on the RUUDY FOUR RNAV departure. Initial climb [was] to cross WENTZ at 1;500 FT. While the aircraft was capturing the altitude; the First Officer reengaged the Flight Level Change button which caused the aircraft to continue to climb. I noticed the altitude did not capture; and disengaged the autopilot to stop the climb. We climbed to 1;800 FT momentarily and quickly returned to 1;500 FT. There were no traffic conflicts or other issues. The First Officer had recently received his type rating on the Gulfstream 550 and this was his second trip. I explained to him that the Flight Level Change button while engaged would capture and level the aircraft at the selected altitude. He understood the mistake which caused us to overshoot our altitude. This has been addressed and I am confident this will not happen again.
A G550 Captain was flying the TEB RUUDY FOUR RNAV and as the aircraft was leveling the First Officer engaged the Flight Level Change button which caused it to overshoot 1;500 FT.
