We just went through this process with my son - He’s an unranked C-rated fencer who will fence at Haverford next year,
He put together a one page academic and fencing resume and sent it out to the coaches along with rec from his club coach, and then met with some of the coaches at Summer Nationals and other NAC’s and made some college visits.
We looked online at the college rosters and cross-checked the foilist with Askfred to see where he was a comparable fencer.
The ones on your list we visited were:
Haverford - My son liked their fencing room, the coach and the guys on the team, and, of course the college.
Brown - Coach was sort of aloof - looked like they practiced on a multipurpose gym floor - not so good IMO. My D is a junior there and loves the University, but she’s not a fencer.
Lafayette - the coach set up a meeting for us with a team member (coach was out of town). The guy bailed on us, but we toured the college and gym. From what we gathered there was no exclusive designated fencing room.
Lawrence - S met with the coach (I think he is new) at a tournament, but did not visit. Lawrence does have a free application, minimal essay, and nonbinding Early Action, so you can get a December decision.
Other schools we visited where we felt he could have fenced were;
UNC Chapel Hill - great facilities and DI athletic treatment (special perks) and a large roster.
Air Force Academy - Father-like coach. Team, coach and practice provides some respite from military rigor.
Johns Hopkins - Nice fencing facility.
Stevens Institute of Technology - Very nice coach from Northwestern. School sits on a river bluff overlooking Manhattan. Good Co-op program and job placement.
Hope this helps
