The International School St. Gallen was founded in 2009, as a full-day English-speaking international school consisting of a Kindergarten and a primary school. The school was started under the leadership of Mr. Stefan Preisig, who was the head of school in its first two years, building strong foundations within the school’s structure and local community along with the SBW Haus des Lernens, who operated the school.
ISSG was authorized by the International Baccalaureate Organization in November 2013.
Since January 2015, ISSG is no longer under the management of the SBW Haus des Lernens and has started a cooperation with the ISR International School Rheintal. Now the two international schools in the canton St. Gallen create a strong option for international families moving to the 4-country area at the Lake of Constance (Bodensee Region) including Switzerland, Germany, Austria and Lichtenstein.
