Kumon Leysin Academy of Switzerland

KLAS offers a three-year high school program (grades 10–12) with about 45 students per grade and 27 full-time teachers. In the upper grades, students choose between the Main Bilingual Program (MBP) and the Advanced English Program (AEP), with a wide selection of English courses and elective options in English or Japanese. The program develops English and French language skills while continuing to support the mother tongue, Japanese, in line with Japanese education requirements. In Term 1 of the 12th grade, students may participate in the Summer Abroad Program (SAP) at universities in the USA or the UK, or study on campus through Summer in Leysin (SIL), which includes ESL and English-taught content classes.

KLAS offers substantial arts involvement, including a Musical Production that has been staged since 1995, with four months of rehearsals, an on-stage orchestra, and stage lighting and props. The production engages a large portion of the student body, roughly one‑third, in this major school-wide activity. Additional arts opportunities include private music and language lessons, choir, and concert band club.

KLAS operates an Exchange Program with two sister schools in Winnipeg, Canada; students spend the first half of Term 1 at KLAS, and partner students visit in Canada, fostering cross-cultural exchange. The school also conducts Cultural Trips, with fall Swiss trips to Zurich, Lugano, Bern, Geneva, and Lucerne, and spring European trips to Budapest, Prague, Florence, Vienna, Munich, and Barcelona; students write reports in English on these experiences and may receive awards. Model United Nations has been active since 1998, with a yearly Hague MUN trip and preparatory meetings to study UN issues and country assignments.

All students participate in at least two supervised afternoon activities each week, choosing from a range of sports such as badminton, basketball, running, skiing, soccer, snowboarding, swimming, tennis, and volleyball. Non-competitive sports including fitness, ice-skating, mountain biking, squash, and trekking are also available. Additional options include private music and language lessons, choir, concert band club, Model United Nations, and college guidance. In winter Leysin's ski season provides two full afternoons of ski or snowboard instruction, with the school's ski and snowboard teams competing against other schools.

Optional trips are organized in spring and summer breaks, and there are humanitarian and field trips arranged by faculty. Exchange Program fosters international interaction and cultural exposure beyond the classroom.

KLAS has two college guidance counselors—one for Japanese universities and one for non-Japanese universities—to advise students in college selection and placement. There are three tracks (Track 1 for Japanese universities, Track 2 for non-Japanese universities, Track 3 for undecided) that begin in tenth grade and continue after graduation, with the academic department coordinating course selection. Counselors coordinate college fairs and arrange visits from college representatives to KLAS. Model United Nations participation also develops leadership and awareness of global issues.

Dormitory Life is supported by dedicated dorm parents for both boys and girls, who oversee dorm life and provide guidance. The daily schedule balances class time, recreational and sports activities, and independent study, with at least two after-school activities and a weekly study hall. Afternoon Activities include interscholastic sports and non-competitive options, with Winter Activities offering two afternoons of skiing or snowboarding each week and competition by the school's ski and snowboard teams. It is common for students to experience a sense of community and personal growth through boarding life and structured routines.
