Since the parents chose a Christian HS for her they definitely need to consider the nonacademic fit as well as the academics. Some schools may offend the parents with the campus atmosphere. If she leans heavily towards STEM subjects she should concentrate on schools where she will find many like minded students. It is much easier to be among those with the same interests than at a heavy humanities LAC. Right now I suspect she is naïve about the possibilities in science as exposure to a school where the majority of science students are not premed may be best. That said- consider Washington U in St Louis as a school with opportunities to become involved in things medical as an undergrad.
I cringe at considering LACs having “great science facilities” since there is no way they have the opportunities to be in grad labs like at research U’s during their undergrad science courses.
