I believe it's also age 4 here.
They will reimburse up to 125,000 per year. You can spend it all on one kid or pay for 3 different kids....for example you could spend 100,000 on 1 child and 25000 on the other.
This amount is adequate for 3 young kids at most schools but for some of the more expensive ones it is not.....for example the American School is approximately 75000 per year per student.
