The Vientiane International School Board of Trustees is a nine-member volunteer group of parents committed to the mission of the school which is to challenge, inspire and empower students to develop their unique potential in our changing world.

The purpose of the Board of Trustees is to ensure that the school delivers on the mission, vision, values, and destiny plans while maintaining the resources and capacity to secure long-term sustainability.
