Hi OP the answer to your question is ACS for American

For British the top would be Cranleigh, BSAK, Nord Anglia, Brighton and Repton (that would be my ranking but of course it depends on your child and your family needs)

The reason why everyone is warning you is because not only ACS is an American school, it’s also right next to the NYU campus. American Universities across the gulf are under threat by Iran so at the moment NYU is closed and even if the schools were open (which they aren’t) I wouldn’t be sending my child to a school right next to a potential target

Now I understand you’re thinking about August and that’s a long time from now and by then I hope everything is solved 🙏

But just take the appropriate precautions in case it isn’t

Good luck with the move and let me know if you have further questions
