I know nothing about prep school finances. How many kids would you say was healthy/ safe from going bust in a 3-13? Can a school with 250 on role be relied upon to stay open? Is there a number you would say is too small to be a 'safe bet'?
Also, in terms of decent sports, drama, having enough people to choose friends from etc what would you say for the minimum in a year group?
I'm debating small v large as part of my final decision. DS is August born and I don't want him to get lost, but equally I don't want to put him in a school where he has to have 3 parts in the annual play and then have it close half way through year 6.
