My soon to be ex grew up in Nyon and went to the internaional school of Geneva and had advised that this is the only english speaking school they can go to. I did ask him about Catholic schools in Geneva or Vaud and his dismissed this and told me they are not in the area. My boys are 11,8, and 4, after discussing Switzerland with my boys there main concern was not knowing enough french to attend a local school. Currently here in the UK they are at the top of their class at present and I on't want them to fall behind. Thank you for the attached link.
