THE continued influx of expatriates, the lure of a ‘‘portable diploma’’ in the form of the International Baccalaureate (IB), the concern of providing a safe learning environment for children of families living in the world’s trouble spots, and the desire of local Swiss residents for alternatives to the state educational system are four reasons why Switzerland’s extensive network of international schools remains stretched to its limits.
‘‘Expansion is going on throughout the country to meet the demand,’’ says Alfonso Orsini, headmaster of the Leysin American School and chair of the Swiss Group of International Schools.
