The American School of Madrid was established as an independent, American, non-profit, college-preparatory school under the form of an Association. It is governed by a Board of Trustees whose primary responsibility is to keep ASM’s founding mission current and viable. The Board is a policy-making group, legally empowered to act on behalf of the School. The Board charts a course of action for the school through the development and adoption of Board policies and decisions.

The by-laws require that the Board is self-perpetuating and that members represent ASM, not a particular constituency. The Board represents a large diversity in talents, including business, financial, professional, and other skills.
