“But I’ve seen that a 1500 is required to be invited for scholarship weekend. Any information you have on that?”
I am not sure. I heard that the kids in my son’s class (sophomores) that are Stamps Fellows were in the 34 or 35 ACT range. My son is an international student so did not have to submit SATs. I’m not sure what the current 25%/75% SAT range is as the CDS lists it in the old SAT format, but (in my opinion) I think that a 1480 SAT and a near perfect UW GPA should get your kid at least an invite. If you haven’t yet, you should definitely do a campus visit and have your kid reach out and contact the regional adcom to express interest.
