One thing to consider is I find that student athletes that have attended prep schools are very well prepared to balance the academic and athletic demands of college. You daughter can even “re-class” so that she will have more advanced classes before applying.
There are great boarding schools with girls ice hockey that you don’t hear about often on this site. Look at the “Hidden Gems” thread and you will see lots of less familiar names.
You can also look at the rosters of colleges you think she would be likely to attend and see where their players are coming from.
