They both took the exam but I think they were probably undecided about day vs. boarding at that point. One of them took up his place and had just started as a boarder now anyway. From what I hear he is very happy there too. The other family decided boarding was not for them and their son is at KES. My point really was that I don't think it is competitive as some other schools. Good luck to your son - I was always desperate to go to boarding school as a child!
Parents often apply for day boarder and then put down for boarding also as back up in case they don't get in via the exam. Quite a few boarders live locally as a result.
Last year for the 16 places they offered into the 30's from the exam.
Boarding places is purely on a suitability to board assessment which includes an interview.
