We live about two miles from the original Sudbury school in Framingham, MA, and a neighbor has incredibly good things to say about it (her children, all in college now, attended throughout their K-12 years), so we've tried to check it out. Unfortunately when my husband called about it, and expressed interest in visiting the campus, he was told unequivocally: "no." He was quite taken aback. Apparently their policy is that no one (besides students) can visit the campus, unless they go through with the admissions process (cost: $50) and get an official interview. We were quite disappointed with this rather negative response. Our dd is only two and a half, and we're just in the beginning process of visiting and thinking about schools -- we don't really want to give them $50 just to get a feel for the place. We still believe in the philosophy, and may in fact end up sending dd there, but it wasn't a great way to start the relationship....
By the way, tuition at the original SVS is a bit over $5,000, which I think is quite reasonable, especially after seeing the tuitions at other private Boston-area schools!
