Narrative:

Departing teb we are assigned the teb 5 departure. Sic was left seat and flying. After conducting a noise abatement takeoff we climbed to 1500 ft and made the right turn to 280 degree heading. I was head down completing the after takeoff checklist when I heard the altitude alerter. Looking up; the sic was climbing through 1700 ft. I noticed that we were only 2.8 DME instead of the required 4.5 DME for climbing to 2000 ft MSL. Instructed the sic to descend back to 1500 ft MSL until the 4.5 DME then climb to 2000 ft. ATC called and indicated that we climbed too early. The departure was properly briefed.
