School Leadership & Governance

The ISS governance structure is comprised of an Executive Board and a Supervisory Board. The overall operational responsibility of the school, in accordance with the School Articles of Association, rests with the Executive Board, consisting of the School Director. This operational authority covers both campuses of the International School of Stuttgart.

The School Director therefore meets regularly with parental organizations and provides forum opportunities for various constituencies to share their thoughts directly to the Executive Board.

When implementing strategic, operational, and pastoral initiatives, the School Director works with the Whole School Strategic Leadership Team, which consists of the Business Director, the Division Principals, the Head of Campus in Sindelfingen, the Director of Admissions and Enrolment, the Human Resources Manager, the Strategic Development Manager, the Admissions and Office Manager and the Director of Information Technology.

Specific Divisional educational responsibilities are addressed by Divisional Leadership Teams for each campus. These teams consist of a Principal, an Assistant Principal, the IB Program Coordinator, and additional leaders as per divisional needs. Programmatic leadership is provided by members of the whole school IB Council which consists of the IB Program coordinators.

In order for ISS to function well, we have many people who are involved in leading the school, and they work in teams, just like we often do. There is a Board of Trustees, who are elected parents, and they volunteer their time to provide guidance. Then there are the School Director, Principals, and other people who work in the school.

Supervisory Fiscal and Strategic Leadership

ISS is a private, non-profit institution (Verein or Association). All parents and teachers are automatically members of the Association, which gives parents the right to be elected as a voting member of the Board of Trustees, and/or to vote on issues at AGMs. The Board of Trustees comprise the ISS Supervisory Board and members are elected to serve a four-year term of office and devote their time and energies on a voluntary basis.

The Board of Trustees serves as the strategic leadership body of the school and as such, advises and evaluates the operational Executive Board, currently the School Director. The Director bears responsibility for the day-to-day operational concerns of the school and is a non-voting member of the Board of Trustees. The Board of Trustees guides the Director’s leadership through the Strategic Plan and the Board Policy Manual, which is annually updated and reviewed.

Focused towards common board goals, the Board of Trustees divides its work across a number of standing committees that meet to research and discuss issues to be brought to the Board for decision or information. These standing committees are: Finance, Education, Development and Policy.
