Yes. Now I see the difference 
@ThacherParent, Thank you again!
As @soxmom noted EHS resides in an urban, major metro setting and thus ethic diversity is a non-issue. With that said, BS can be an ivory tower somewhat insulated from its surroundings. Within the EHS gates, the student body is well represented by many ethic backgrounds.
The campus architecture looks Jeffersonian, which to a Northerner like me, feels like the south, albeit, not the deep south. I love the campus. Very relaxed. Beautiful in the springtime with all the cherry blossoms. It only 140 acres, the right size IMHO. Easy to navigate, plenty of open space, and the facilities are better than some colleges. To folks from the South, it is known as “The High School.” Unlike the long list of BS’s in NE, there are not many south of D.C. When families consider a private BS for their children, and they prefer to stay within 500 miles, EHS is high on the list. This is why there are many students from Virginia and the Southeast region.
@i70sband Thanks. AO was very kind and helpful at the informational meeting too! We will definitely apply either for 2016 or 2017.
It’s hard to imagine a better school for indoor or outdoor climbing than Colorado Rocky Mountain School. This is a rarely discussed school but they produce more professional outdoor athletes than any other boarding school. The school has topnotch indoor competitive climbing and access to some of the world’s best natural climbing. Just thought I’d chime in with a very special school with incredible climbing resources.
@hola3, Thank you. It’s an amazing school for sports as well as art! Are you familiar with the school? Any other information? How is the school’s academics? What is average academic strength of the students?
If you’re interested, send me a PM. I can get you in touch with the head of admissions who is a wonderful resource. I have taught in BS for fifteen years and my little sister graduated from CRMS not too long ago. It’s a unique and inspiring community.
Putney has a wall… they make expeditions, ice and rock … as I’ve described before… if a child wants to pursue something… the school will back them up. Arts, Academics… design your pursuit, it’s Progressive education through experiential learning.
Did this same search 3 years ago - Berkshire, White Mountain and Proctor all offer climbing. Mercersberg also has a climbing team I think. Some of the Boston schools climb at MetroRock. For competitive climbing, a “hobby” wall won’t be sufficient for training properly - and I think White Mountain is the only school with a full-size gym. Transportation is also an issue if there is not a regular program in place. My daughter ended up switching sports and found a lot of friends in similar straights (dancers, skaters etc). Choatiemom can confirm but I think Choate students are walking distance to a climbing gym but I don’t know if the school utilizes the facility. Hope this helps! PM me if you like.
Wish I could be more help, but I only know that Choate has a climbing wall. I don’t know if it’s competitive or hobby as I didn’t know there was a distinction. Maybe someone else with experience in this sport can set the record straight. 
The Mercersburg program seems fairly intense…my beginner son has spent a number of Saturdays on long climbing expeditions (some outdoor, some to larger indoor facilities), this in addition to every day after school. I believe it is only offered in the fall, although I’m not sure because my son has other sports the other terms.
Below is a reply I got Choate; “Our rock climbing through the school is an intramural program so we do not compete in any form. It is offered in the fall and spring and is four times a week for an hour. Sometimes they go to other places to climb but not too often. Depending on the popularity will determine how many students there are in the program. Usually its around 10 if I recall correctly. If your daughter is a serious rock climber and has a mode of transportation there are some local places to climb and she could sign up for an approved project as a sophomore, junior or senior in order to climb on her own a compete instead of doing a choate sport. We encourage all of our students to stay in Choate sports but we do allow some special circumstances esp if she competes in the sport.”
Daughter liked sound of the program. 4 hours per week is the same as she is doing now and feels ideal. She enjoys regular conditioning and practicing, but is not really into competitions either. And not having have to bused to an outside gym, no matter how close that is, a huge bonus. Also she would rather focus on indoor climbing instead of mixing outdoor climbing, which is a very different sport.
She also became more confident in her ability to tackle academic rigors of very challenging schools like Choate.
If the very competitive school will like her back is a question of course.
Of the schools mentioned above my guess is Choate and Mercersberg are the strongest academically. Good luck to your daughter! Many colleges are adding rock climbing too now as the sport grows in popularity in the US.
