My daughter’s first campus visit we made the mistake of her dressing like a typical college student. Very bad. Coaches are not interested in recruiting students. They are looking for athletes/players. Wear clean athletic shirt pants/shorts shoes and socks that fit with your sport. Nothing from another college. Look like you are able to join in a sideline warm up for whatever sport. You can’t join a practice (unless a camp is ongoing). But, this is how you typically “meet” other players. My daughter was a soccer kid. The ability to stand on a sideline casually juggling, while chatting, probably resulted in a couple offers.
These player “meetings” are NOT accidental or casual. The coach will be getting reports from the players. Yes - you can ask them real questions. That is fine. Do NOT discuss your partying habits. All contacts are part of the interview. Have some real questions to ask.
For girls in particular, it would be a good idea to already know how to use weight room machines and free weights. The tour will include the training areas. “We do weight training. Do you lift?” If your kid can answer - “Sure, I do abc, def and xyz mostly.” That is very good. Know if you are comfortable with free weights. It’s fine not to be. Most high schools do not have free weights so it’s not a surprise if you don’t do free weight.
It’s good to know your own scores/bests for standard stuff for your sport. For soccer, knowing your beep test score, the Cooper Test and FIFA shuttle test are pretty standard.
Have 5 questions/discussions planned for the coach. Coaches are often bad at interviewing, and players you talk to will be worse. Some where along the line the coach will ask; “Do you have any questions”? Have some in your pocket ready to go. Practice asking them to adult friends of parents so you get good at asking and they sound natural. Interviewing is hard work but practice makes it easier. My kid - for soccer - had pretty good success with questions on team formations. Her club coach helped come up with them. “I watched the games against abc and xyz and it looks like you use a (formation) do you change based on your players or competition? Where do you see me fitting in?” Coaches loved that she watched games. Ask players about team travel is good. Bus, fly, hours, getting class work done, study requirements etc?
My daughter did 12 campus visits counting the disastrous first one. By the end she was getting pretty good and everyone was making offers. She was not a national team/future pro player. But, she got to be good at the process. If you are making the campus visit you are already good on the sport assessment. Treat the visit as an interview with the goal of getting an offer. Whether you ultimately take the offer is different. You are going to say “thank you, thank you. it’s really exciting. I can’t wait to talk to my parents and tell them. They probably will have questions. Who do they call.”
