We are in the “Revisit Days are Very Important” camp.
If your kid is an Athlete, Speech and Debater, Robotics or Math kid, Artist or Musician: a well-organized school will have kids from these areas spend the day with your child/family. Yours will get a good feel for those they will be spending a lot of time with over the next 3-4 years.
Parents will get a chance to meet the Head of School and/or senior leadership, and meet other prospective parents and kids.
If there is any feasible way at all to attend 2-3 of your family’s top choices, I encourage you to do so.
Even if you have only one school choice - go visit if possible and only if it doesn’t stretch your finances too much. Your kid will be psyched until September.
