If a school is a D1 school, it is D1 for everything. There is no such thing as a school with D1 football and D2 or D3 wrestling. D1 schools can’t ‘play down.’
If a school is a D3, it can petition to ‘play up’ in 2 sports, one male and one female and there are a bunch of sports that are really just one division (bowling, rifle) so the schools can do those too. Most do it for hockey (Colorado College, Union, St. Lawrence), Hopkins does it for lacrosse.
I think wrestling has championships in every division so it would be hard to ‘play up’.
Is that what you meant or is he looking for a D1 school near a D2/D3 school?
