Have you visited Lawrence? It sounds like a great fit, and we really, really liked it when we visited; but a proof-of-concept visit would be important before ED’ing. If she’s a strong enough swimmer for their D3 team, that could also contribute to nailing down an ED acceptance. They’re test-optional too, although any improvement in your d’s scores could put her into that gray area where sending vs. withholding could be a wash. According to CollegeData, there’s an 86% Early Action admit rate, so you don’t even have to do a binding application to get the boost. (Add to that the fact that it isn’t a need-blind school, so they’ll be aware of your willingness to go full-pay minus any merit offered, and I think your d’s odds in the EA cycle are excellent.) We found both the admissions folks and the student hosts to be among the most welcoming and genuine of any we met in far-too-many college visits for two kids. My d’s only criticism was that while it replicated everything she loved about her performing arts high school (as far as music being central to the social life, people being friendly and supportive, etc), the fact that she’d already had that experience made it feel almost too familiar and comfortable. But not everybody gets to have a high school that feels like that!
Bard is another LAC+conservatory school with a similar stat profile to Lawrence, but a lower acceptance rate (presumably attributable mostly to geography). I haven’t ever visited there but my impression is that the vibe/culture is quite different from Lawrence, probably largely due to the different geographic mix (similar concentration of NY/Northeast students at Bard to WI/Midwest students at Lawrence). I would think most people would have a clear preference, personality-wise, between the two. Bard is test-optional as well, and also has D3 swimming. Not a big ED/EA boost there, though.
On the other coast, Chapman is another you might look at. She’s right in there stat-wise and it’s another great school for combining music with an academic major. The Southern California vibe (a stone’s throw from Disneyland) is yet again very different from both Lawrence and Bard; I’ve known a number of young musicians who have been very happy there.
If you think your d is a D3 swim candidate, have her start filling out prospective student forms on the athletic department websites. There’s no harm in getting on radar - it’s another way of showing interest in the school, which can only help.
