Our kids are in a fee-paying school. My husband is a teacher at that school. There is no way we could afford to send our kids to the school where he teaches unless they offered us a big discount on tuition...which they do, and even then our school fees are more than our rent...and we have a third child who will need to go to school in a couple of years...

However, I go on my father's advice -
- invest in the early years, they are the foundation for life
- and if you have any cash left over, save it to buy your kid a place at university in whatever course they want to do...

We are happy with our choice of a bilingual school for our children because we are planning for the eldest to go to do secondary and tertiary education in English...and our middle child is in 2nd class with a native (high) German speaker and a native (Canadian) english speaker...

However, as everyone else has said, if you are planning to integrate, that means doing secondary and tertiary studies in one of the national languages... or save a lot of pennies so they can study outside of Switzerland...

Oh, yes and as the daughter of a teacher as well as the wife of one, there are LOTS of good reasons why not to put your child into the school where you work...
