Sycamore School costs a lot of money. They don't hide it, starting with the $175 assesment fee you are charged to have "experts" watch your two and a half year old play for a half hour in order to determine if they are advanced enough to join their programs.
After looking at several private gradeschools, we opted out of this one. It places heavy emphasis on academics, employing great teachers and only admitting the best and brightest. Although we (like all parents) feel our child is up to it, we felt it was far too rigorous and not playful enough.
I have several friends who teach here and I believe in it for an education, but be sure you know the mission statement before signing up.
