Anything a student tour guide reports is not going to have much, if any impact on admissions unless it is especially egregious. More likely it would be used to get more information on the student’s interests. I don’t think my daughter was ever asked to give her personal opinion of a visitor when she gave tours.
How many schools you can do will depend on how close together they are. For instance, it would be very easy to do Middlesex and Concord Academy together because they’re about 3 miles apart and CA is 2 blocks from a bunch of lunch spots in Concord Center. Likewise, Groton and Lawrence Academy, both in Groton MA, and Brooks and Phillips Andover, in North Andover and Andover. My advice, from having done both college and prep school trips with my kids, is to schedule 2 visits a day, one first thing in the morning and another in the afternoon, then drive to the closest hotel to next morning’s school. That way you can preview the route to the morning’s school and you won’t be stressed over getting up early to make it to the interview.
I’d recommend taking the official tour (which is generally scheduled as part of the interview process anyway) then, if you have time, walking around school to observe. After an afternoon interview a great way to get to know the ethos of the school is to go to a sports match and hang out with the parents on the sidelines and ask questions. Most parents will be happy to chat with you about the school and you’ll get a more unfiltered opinion of that school and others with which they have experience. Ask not only about the school you’re visiting, but about what the family liked and disliked about other schools they considered and why they made the choice they did, although you should of course take any negative opinions with a grain of salt and confirm any information you hear independently.
I crossed a school off our list after hearing from two different parents at our older child’s sports events that a school we were considering for our younger child didn’t readily offer the support she needed despite the school’s official advertisement to the contrary. When, based on these conversations, we pushed the school for particulars on their support system it was clear it wasn’t a school strength. Likewise sideline conversations with parents helped us to confirm some positives we’d heard about schools. In one case what was for another family was a negative was for ours a plus.
A few things to remember-
Do some research on the school before arriving. Your child should have some idea of what appeals to her about the school in advance. Have her take notes after each visit so she can distinguish between them later.
I’d wait to write the application until after the visit. That way your child can reflect on what she found attractive in the school community when she was there.
The schools are looking for a fit between the family and school so they’ll talk with you, the parents, as well as your child. Be prepared to talk about what you’re looking for in a school (greater challenge? support? arts opportunities? diversity? a fresh start?) and about your child’s strengths and weaknesses.
Many schools have parent liaisons in the admissions lounge, and they can also be a good resource.
@msvmp27, Would you mind divulging the schools you’ve already decided to visit? Many parents here have experience with the Boston area prep schools and could give you good advice on traffic, lodging, and schools to add to your list.
