If you are really considering it, you might want to look into "American Schools" in Italy. These are schools that teach in English and cater to Americans living temporarily in Italy who plan on returning to the US. These schools follow a traditional American program of study and allow the kids of American (and British) businessmen to move without missing a step in school. Here is a website with info on some of them. You have to be a EU citizen to work in most of them.
