Narrative:

We were given an altitude of 11;000 ft; but we put 12;000 ft in the altitude select without noticing. We noticed this climbing through about 11;400 ft and immediately corrected back down to 11;000 ft. Due to our high climb rate we reached nearly 12;000 ft before getting the airplane descending. I do not believe there were any aircraft conflicts and nothing was said to us by departure. I believe there were 3 factors that contributed to this event; beside just a failure of verifying the altitude selected. 1. Our duty time: 13 hours into our duty day. So I believe fatigue played a factor.2. This was a short 20 minute flight. Due to the short flight time it makes for a busy cockpit environment.3. Our climb rate was around 4;000 FPM because we were light (weight). If we had slowed our climb rate we may have noticed and corrected sooner. I believe our flight department should address slowing our climb rate as we near level-off altitude.

Title: G150 Captain reports being assigned 11;000 FT by Departure Control but setting 12;000 FT in the altitude select window. This is detected passing 11;400 FT but 12;000 FT is reached before the climb is stopped. Fatigue and a very high climb rate were cited as factors.
