What kind of experience is she looking for? Scripps will be the small liberal arts school experience; even all the Claremont Colleges together is still quite a small community, and she will have small classes with lots of interaction with classmates and professors. The University of Virginia and JMU will be larger, more traditional/stereotypical Big U experiences: Greek life, big sports, etc., especially in the case of UVa. UVa has the nice benefit of having this atmosphere and having a reputation as a highly intellectual school (and it is technically on the small side for a Big U).
William & Mary will be in the middle - medium-sized student body, and it strongly identifies as a small research university, where professors will do research but are scholar-teachers and invested in supporting both.
It doesn’t look like either W&M or Scripps require application into their CS major. Someone above says UVa does, so that’s a consideration.
I went to a small women’s LAC within a larger consortium of colleges/universities, and I really loved the experience. You get the best of both words: A women’s college and a small LAC environment with lots of other college students nearby for socializing, student groups, and learning from one another.
