Overall, this is not a bad place to be! But I understand the stress – our family went through this as well.
I would, first and foremost, have her really dig into the websites to review the programs, the requirements for graduation, distribution requirements, availability of courses, etc. Are some more geared toward an academic, grad-school bound student while others are intended more for practitioners? Is one preferable? If she wants to experiment in other departments or change her major, how much flexibility is there to do that? Or is she certain of her path? As a result of this, are there any schools that she wants to drop from the list?
What is offered in dance in terms of courses and performance opportunities? How competitive is it to get into classes and companies? Can she meet some of the other dancers at a re-visit?
Is there anything else that she would like to see as part of her four years, like study abroad, or internships, and how easy will it be to do that with her major?
She should explore some of these, as well as dining and living options, on re-visits. I feel like a lone voice on these boards suggesting that you re-visit all the schools that seem to be real contenders rather than narrowing it first. Yes, it takes time and is hard given school, ECs, sports, etc., but my goodness! This is a BIG investment of $ and time, and 4 years of her life! She should be thoughtful about it. And it will also help her learn how to make big decisions and maybe a little about herself. It is very different to look at a school as a prospective student rather than as a prospective applicant. I was honestly a bit surprised about which schools moved up on the list during re-visits, and I think part of it was also that by spring of senior year, the perspective on this is a little different too.
One of the things that DS found was that sometimes, something that sounds really “cool” about a school and that propelled it to the top of the list was something that was not unique to the school, and that is something that one finds only by making a couple of visits. She should also really try to evaluate the vibe and culture. Does she feel like she “fits”? DS noticed that at some schools, all the kids would talk to each other before and after class whereas at others, they’d walk in and out silently. At some, people went out of their way to help him find a classroom or navigate the dining hall. Those little things may be quite telling. But I think that after several visits, he became a little less “deer in the headlights” and a little more observant and more tuned in to where he’d be happy.
The important thing that he did, though, was (much as your daughter is doing) was establish front-runners. After each visit, he’d ask “if I had to choose between X & Y, which would a choose.” And the winner would be compared to the next choice. At no point did he ever have more than 2 or 3 that had been visited in serious contention. When he ended up with the final two, the one with the better merit aid won out.
If your DD is stressing at the end, remind her it’s because she’s having trouble seeing the difference, and that likely means that it is negligible and that she’ll be happy at either.
