I’d just sign her up to take the ACT or SAT next opportunity. Like now. You can still sign up for the February ACT right now with late fee. Then if she needs it, she has 1-2 more chances. Especially if you don’t have a baseline with something like a PSAT score or an early ACT/SAT.
I would not push the parental alma maters if she’s not interested. That doesn’t seem to buy you much in admissions these days anyway.
