Since your hubby is an alum, I’d advise that HE contact the head of admissions, or the Alumni admissions rep, and ask point blank if your HS is on some sort of"no- accept" list. He should state that the question is based entirely on a close review of Naviance info, not on any scuttlebut. He just wants to know the truth- not your DD chances.
He should also mention that your DD IS interested in applying ED there, but you as parents dont want to OK that step if it will be a waste of everyone’s time.
