Best boarding schools in the world: Conclusion
Choosing your child’s school is a big decision, and we understand that it can be daunting.

The right school can make all the difference in helping your child grow into a confident young person who is unafraid of taking on challenges.
We would recommend one piece of advice: don’t choose a school for your child, instead choose a school with him or her. Your child’s excitement (or lack thereof) should play a part in your decision.
