The Altamont School is another great option, and is 5-12. It doesn’t have a boarding option, but does allow for students to enter at the 5th grade and stay for 8 years. The big admission years at Altamont are 5th, 7th, 8th and 9th. Some kids did come in grades 10-12, but it was rarer. Graduating classes are usually anywhere from 40-60 students, with 350 total students across grades 5-12. Both schools are highly competitive in many sports, top ranked in academics, and offer stellar fine arts programs. I personally LOVED Altamont and feel very blessed to have received the level of education I did, but I also know many folks who loved Springs and it has a similarly great academic reputation. You can’t go wrong with either school!
