Any international school primary section intake accept application from a K3 kid

Hi all,

I understand that many international school primary section intake requires people around 4 to 5 year old kid (K2 level) to apply. My kid is now K2 and is going to apply some local schools in the coming September. How about international school Is there anyone of them accept a K3 kid to apply for their first year? For example, I understand that ISF accept K3 student application years before. However, after it opens the class of reception year, they again accept people from K2.
