The easiest ways to start are to find a few schools that have girls ice hockey and then see which other schools are on their schedule. For example, Dana Hall and Choate.
I doubt that the BS offers were fully unsolicited unless the coaches also were BS coaches. Which is to say, you’ll need to do some of the legwork here. Reach out to the coaches with some highlight reels. But you’ll also have to do this at schools which genuinely interest your D, with a full understanding of what’s involved in having a compelling application (visits, tours, interviews, test scores, essays, etc.) That is going to be an important part of the process- nobody is going to offer her a free ride without her jumping through all the hoops.
While there is sometimes money for “merit”, most BS financial aid is based on need. It is also often quite generous. So you are probably going to pay something.
This is all to say that the parents who report that this all fell into their laps are probably omitting some key details AND that a talented athlete who is academically driven can do well in BS admissions if you do your part with diligence.
