Zurich International School
The Zurich International School is a Swiss non-profit foundation (Stiftung) established under Articles 80–89a of the Swiss Civil Code and entered in the Commercial Register of the Canton of Zurich under UID CHE-106.940.379. Its registered office is at Steinacherstrasse 140, 8820 Wädenswil, Switzerland. The foundation was first entered in the register on 10 March 1998 under the name The International Primary School of Zurich and was renamed The Zurich International School on 4 February 2002. It is recorded as active and is subject to supervision by the BVG and Foundation Supervisory Authority of the Canton of Zurich (BVS). Its registered purpose is the operation of one or more non-profit, non-denominational, non-political private schools.
Trading as Zurich International School (ZIS), the foundation operates an English-medium international day school formed in 2001 through the merger of two predecessor institutions, the American International School of Zurich (founded 1963) and the International Primary School of Zurich (opened 1970). ZIS runs two campuses: an Early Childhood and Lower School campus in Wädenswil for ages 3 to 11, and a Secondary Campus in Adliswil for Middle School and Upper School students aged 11 to 18. A third campus in Baden operated from 2008 to 2015 before closing due to insufficient enrolment.
Instruction is primarily in English. German is a required subject from Pre-Kindergarten through Grade 9, other than for students in English-as-an-Additional-Language programmes, and students may choose French or Spanish from Grade 6 onward. The Upper School offers the International Baccalaureate Diploma Programme alongside Advanced Placement courses; ZIS is accredited by the Council of International Schools and the New England Association of Schools and Colleges and operates as an IB World School, though its Upper School diploma is not recognised as a Swiss federal Mittelschule qualification. Independent school profiles have reported enrolment of more than 1,300 students from over 50 countries, though ZIS’s own site does not publish a current, dated enrolment figure.

Shareholders
Ownership and governance of The Zurich International School
The Zurich International School is registered as a non-profit foundation (Stiftung) under Articles 80–89a of the Swiss Civil Code. Swiss foundations of this type have no share capital, shares or shareholders: a foundation is a dedicated pool of assets governed for a stated purpose rather than an entity that can be owned. No shareholder, UBO or ownership-percentage information therefore exists for this entity, and none should be inferred from its registered structure.
Governance is instead vested in a volunteer Board of Trustees, which oversees the foundation and appoints the School Director responsible for day-to-day operations. The composition of this governing body is set out in the Directors and officers section of this profile.
Data availability
Not applicable. The Zurich International School’s legal form as a Swiss non-profit foundation precludes shareholders or share-based ownership; this is a feature of its legal form rather than a gap in jurisdictional disclosure.

Officers
Directors and officers of The Zurich International School
As a Swiss foundation, The Zurich International School is governed by a volunteer Board of Trustees rather than a conventional board of directors, together with an appointed School Director who holds day-to-day executive responsibility and reports to the Board. Commercial Register data for UID CHE-106.940.379, summarised via northdata.de, indicates a registered signatory structure of a president, a vice president, a director and further board members with signing authority, but does not name individuals in the publicly accessible extract reviewed for this profile.
The school’s own governance page, retrieved 10 September 2026, names the following current Board of Trustees office-holders: Markus Klose, Chairman of the Board (also serving on the Finance Committee); Lola Kinder, Vice Chair (also serving on the Governance Committee); and Camilla Perera-de Wit, Board Secretary and Chair of the Governance Committee. Mary Jane Hogg chairs the Finance Committee and Ceyda Avunduk chairs the Advancement Committee. Nine further trustees are named without committee roles specified: Noelle Ahlberg Kleiterp, Andreas Apitz, Helge Behrends, Stewart Dearden, Andrea Ferrari, Monica Forero Salas, Ann Jameson, Filippo Grippa and Jonathan Toretta. Day-to-day school leadership is held by School Director Elsa Hernández-Donohue, supported by Deputy Director Catherine Jolly, Chief Operating Officer Stefan Mühlemann, Chief Advancement Officer Emma Zigan, Director of Student Life Nick Bentley, and Campus Principals Junlah Madalinski (Wädenswil) and Maggie Wollner (Adliswil). No appointment dates, nationalities or countries of residence are disclosed for any trustee or member of school leadership in the sources reviewed.
Data availability
Partial. The school’s official website discloses current Board of Trustees membership and school leadership by name and role, but does not publish appointment or resignation dates, nationality or country of residence for these individuals, and the Commercial Register extract reviewed does not name the registered signatories individually. This overview reflects information published as of 10 September 2026 and may not capture subsequent board changes.

Group Structure
Group structure of The Zurich International School
The Zurich International School operates as an independent Swiss non-profit foundation. No parent entity, subsidiary or sister-company relationship is disclosed in the Commercial Register extract reviewed for UID CHE-106.940.379, and the foundation’s registered purpose and structure are consistent with operating as a single, standalone entity.
The school’s own website identifies an affiliated US fundraising entity, Zurich International School Foundation, Inc., a Maryland-headquartered 501(c)(3) charitable organisation (EIN 13-6261035) that solicits and channels US tax-deductible donations in support of the school’s philanthropy programmes. No official filing was located establishing a formal parent-subsidiary or ownership relationship between the two organisations, so this is classified as an affiliate relationship on the basis of the school’s own description of the arrangement, rather than as a verified corporate ownership link.
