Obersee Bilingual School

OBS is located at Sihleggstrasse 9, 8832 Wollerau, Switzerland. It sits on the shores of Lake Zurich, about 20 to 30 minutes from Zurich. It is just a 2‑minute walk from a quiet forest and 10 minutes from downtown Pfäffikon, and is easily reachable from the A3 highway.

OBS offers Babycare, Preschool, Kindergarten, Primary School, Middle School, and Upper School.

OBS is a bilingual, international school serving German- and English-speaking students. The language of instruction alternates weekly between German and English from Kindergarten to Grade 6; from Grade 7 the same language is used for each subject for a full year (Mathematics is the exception, with language alternation by semester). From Year 10 onwards, subjects are taught in the language aligned with the chosen school-leaving qualification, with IB Diploma and Federal Matura offered.

OBS+ Learning Support provides support across the curriculum.
