Students here can join, play, and lead in these and all of our clubs and activities. Recent graduates have attended colleges such as Boston College, Emory, Franklin and Marshall, Harvard, Sarah Lawrence College,and the University of North Carolina. One on one college counseling is a big part of what we do, full time, for juniors and seniors. SAT averages are 500 verbal (due to our 40% international boarding population) and 600 in math.
