Here's what I think. To be remarkable within the independent school market, a school needs to do lots of things very well. This enables a diverse population of constituents (students and their families) to sense an entire culture of success.
This is different from having one or two "flagship" programs....usually athletic programs that draw talented kids from all around the world to get major press and prestige college placements. That model strikes me as one dimensional. Proctor's history is unique because we had a flagship program sixty years ago--Learning Skills--that became organic to the community, and transcended "program" to color everything that we do. We support people. Today, it's that simple.
So, for example, it comes as no surprise that we have students offering "Math First Aid" (peer tutorial support) three nights a week. That's just part of the culture.
So if you consider another distinguishing quality, such as "experiential education," that's just one more arena in which Proctor is remarkable. Not the only one. Just one more.
And the most remarkable experiential programs, like Ocean Classroom, Mountain Classroom, Proctor in Spain, European Art Classroom, and Costa Rica become mere extensions of a cultural predisposition here in Andover, New Hampshire.
And somthing like the arts--and all of the non-academic electives that could be catagorized as the arts--are just part of the culture.
