Hello, I have this two choices and I am really not sure about what to do. Could you please give me some suggestions? Pros and cons of each one? Thanks!
Revisit them and see what you think then. Do you want all girls or coed? I’m not sure about the location of Emma Willard (suburban/rural) but Concord is in The center of a suburban town a short distance from Boston. Compare the % of day students at each. I know girls who have been happy at each, At Concord you are not allowed to go back to your dorm during the day, which kind of bothered my son when we were looking, but might not bother others.
Hey, I’m a student at Emma, so if you have any questions I’d be happy to answer them 
And to answer the question about Emma’s location, it’s in more of a suburban part of Troy, but downtown Troy is really close and Albany is right across the river, so there are lots of places to go on the weekend. Probably the main pro is that the classes are awesome (although I’m a little biased), but all of my teachers have been really supportive and I’ve often spoken to them during their office hours. Emma was the perfect school for me, but some cons are that it is an all-girls school (although for me this ended up being a pro, but I know most people don’t like this) and that you can be really busy and stressed, but that’s high school, especially prep schools.
Well Lucy, if you go to Concord Academy you will be in my class >:D<
That’s tough and I think the big picture is: either way you go, you’re heading toward a great school.
My best recommendation is also to attend those revisit days - be open and mindful, and jot down and/or discuss your thoughts afterwards, to help really determine how you feel about each campus/community.
My 2cents - I can see some similarities here, but mostly CA and EW are so very different to me!
I like both CA and EW, but for very different reasons - again, the +/- for me, and mostly shared by my DD. Our +'s are easily someone else’s -'s:
CA
- strong academics
- nice community - diverse, international
+/- co-ed - academic flexibility
- conservative infra-structure
+location - proximity to Boston - campus size - small; use of campus…?
- size
- buildings, esp. the dorms
EW
+strong academics
+nice community - diverse, international, seemed tight and like there’s a group for everyone and the groups were fluid (seemed that way, to us, based on the groups we met – though we don’t know what each class are like for sure)
+/- Female only (mostly a huge plus for us, knowing the impact of co-ed on ed., just a - in missing the boys)
+campus size and use - wow
+campus buildings, esp. the library and dorms
-location - so far out there 
- personal attention: support and advisory
To me, CA’s vibe is conservative, having a more rigid approach to campus rules, classroom learning, etc., and yet they have nice flexibility in academic and enrichment opportunities - such as being able to take more than one foreign lang. at the same time and take part in athletic programming that seems more competitive without being on the level of an ISL’s competitiveness/focus. CA also has a nice art scene happening, in both performing and visual – which is where I see the overlap with EW. However, CA’s art programming seemed - seemed - more for those who have already developed these areas and want to continue their talent.
They both have strong art opportunities, though even that feels differently employed/accessed by and for the community. EW’s programming, teaching, etc., feels more inclusive of both the expert and novice learner, like in the arts and athletics. Again, this is just my perspective - I visited both schools, CA more than once, did a lot of research, and my DD ultimately applied to EW and didn’t apply to CA. She did like CA a lot, but we only wanted to apply to a very few schools. EW did not offer FA, so DD cannot consider
I’m happy to share more of my thoughts PM - in the end, though, know you have two amazing schools to choose from – I really don’t think you can go wrong here! Look closely, ask lots of questions, and really live in the moment on those revisit days. You’ll know. Congratulations and good luck.
I couldn’t get soxgirl to consider an all girls school so we never visited EW, but I researched it pretty thoroughly and I was very impressed. I just thought it seemed like a really interesting place, with lots of cool opportunities and just incredibly supportive of girls. As for CA, there were a lot of things we liked about it, but ultimately the high percentage of day students was the key turnoff for soxgirl who really wants a “true” boarding school environment and she felt like CA wasn’t it. She also didn’t like that boarding students can’t go to their rooms at all during the day. And she was concerned that that high level of talent in the performing arts program meant that she (more enthusiastic than talented) wouldn’t get to participate as fully in theater as she hoped. As a parent, I didn’t love that the kids can (and do) walk into the town of Concord during free periods in the school day. And I was unimpressed by the library, which seems to be a general reaction as I know a number of kids who chose to study in Concord’s town library instead. But the chapel is really gorgeous, and I love the concept of the students giving chapel talks.
All this information is very important and I will be well prepared for the revisiting days. As you are saying, once we are there we will know. Anyway, these are happy times!
I don’t have a kid at CA, so I don’t have a dog in this fight but I’ll still point out that the Concord public library is literally across the street from Concord Academy, so in some cases it may be closer to a student’s dorm than the CA library.
Parental and alumni perspective here. I am an Emma Willard grad from '89, and have spent some time back on campus interacting with students recently and have friends with daughters there. My own son looked at Concord (was waitlisted). They are both wonderful schools. Concord felt the most comfortable to me of all the schools my son looked at, I think because it was smaller and more supportive like Emma Willard.
There is an obvious difference in location. Having Boston at your feet is a huge plus. But Troy is not the pit it used to be. Witness recent NYT article: http://www.nytimes.com/2015/03/29/travel/another-hudson-river-town-reinvents-itself.html?_r=0. I would say it depends upon whether you want to be focused on the boarding school experience or have more city resources available to you.
Generally I would say that Emma operates on its own terms, in many ways. It is geographically removed from the New England boarding school scene. But also, its students are extremely independent, diverse, and just unique. You either love that or you don’t. The academics and community at Emma are great, and the campus is the most beautiful of any school. The alumni network is amazing for a girls school.
Good luck and I don’t think you can go wrong!
My son is a freshman day student at CA and loves it. I am not sure I would describe CA as having a “conservative vibe” in any area, though, so not entirely sure what the poster meant by that. Yes, it is accurate that they don’t want boarders in their rooms during the school day, but I would not describe the academic or classroom structure as conservative or rigid at all–quite the contrary in our limited experience so far. I think it’s hard to compare a coed school with one that isn’t–there are pros and cons of each, to be sure. And to me, CA feels very much like a boarding school–the events and schedules seem designed to make sure day students have to be on campus for school events several weekends per year, a lot of weekend outings and fun events are always on the calendar, etc. My son has a very long commute each day to school, but he feels it’s worth it because he loves CA and loves the mix of boarders and day students. Congrats on your acceptance and good luck with your choice–both sound great!
I realize by now all decisions have likely been made. I’m an Emma parent (GG is just finishing junior year). GG was accepted to both Emma, Concord and a couple of other schools a few years ago, and for a variety of reasons, chose Emma. It has been a rewarding experience, and, though it was the only girls’ school on her list, the fact that it IS a girls’ school has been a real plus. Please feel free to PM me with specific questions; I don’t post frequently these days, but I do check in and will set my notifications so that I at least know there is a message in my inbox!
