My spouse is going to be in New England in April and there are a couple of BS we may add to our Fall interview/application process. Is it OK for a parent to have a solo campus tour in the Spring without the applying student? Our son can’t be there next month because of school/sport commitments.
I don’t see the above as an issue at all. I’m sure most schools would be glad to give your spouse a tour. Depending on your son’s particular sport(s) you might try to meet up with coaches too.
I agree with @BigBlueSwim … I’m sure most schools would entertain just a parent, but I would caution about prior to A10 simply for the purpose of revisit days. There may not be much personal attention prior as most admissions personnel will be prep for Revisits and contracts/matriculation.
