Minnesota and Delaware both have IHSA teams. I didn’t look up the others (I only looked up UMN and UDel because they are both top ChemE schools).
Here’s some info on the UMN team: Minnesota Equestrian-About
But I specifically mentioned UDel because it’s tops in ChemE and because their equestrian team seems pretty strong.
I was also going to mention Minnesota and Delaware as colleges worth checking out–and already done, of course.
In general, though, it looks to me like some careful thought went into the original list, and your daughter has excellent qualifications overall, so I think you are in great shape!
The girl is a Mass resident, so I would think that she’s be more likely at UMass than UNH. I would think UMass would be a lock.
