There is a chapter in one of Malcolm Gladwell’s books (David and Goliath, perhaps?) that has a chapter about college success in STEM fields. While many quibble with Gladwell’s methodology, I believe his overall conclusions are sound in this instance. He argued that students interested in STEM, particularly girls and/or people of color, are much more likely to stick with the program if they are bigger fishes in less competitive ponds. Go to a school that is above your level, feel inadequate in a required freshman weed-out class, and you are likely to switch to some other major, especially if you are not a white male. A second finding he reports is that academics and researchers who went to less prestigious schools often end up publishing more and in better venues than their Ivy peers. So I think Gladwell would advise you to choose a school where your daughter is more likely to stand out, if she wants to attain her goal as an OT/PT. Just one perspective but I hope it is useful for your thinking.
Whatever she decides, remind her that there’s no shame in asking for help if it’s needed and professors can point students to tutoring, study groups, review sessions, and the like.
