The ISL Board is composed of eight to twelve members who are representative of the community, who have shown commitment to the school, and/or who possess skills that are critical to the Board. At ISL, the Board is the guardian of the School and constantly monitors its success in fulfilling its mission. The Board and School Director therefore work in partnership to ensure that all the necessary conditions are provided to fulfil the aims defined by the school, anticipate what the needs might be in the future, and redefine the School’s policies in accordance with those needs.
