About Us
Accreditation
The Montessori School of San Antonio is accredited by the Independent School Association of the Southwest. ISAS is an organization of 89 schools spread across Texas, New Mexico, Oklahoma, Arkansas, Kansas, and Louisiana. ISAS is recognized by the Texas Private School Accreditation Commission. Other local schools accredited by ISAS include San Antonio Academy, St. Luke’s, Saint Mary’s Hall, Keystone School, and TMI.
ISAS accreditation requires adherence to a set of rigorous standards of best practices of independent schools. Following a thorough self-study, an accreditation team composed of experts from other ISAS schools conducts a three-day visit every 10 years, scrutinizing every aspect of the school’s programs and operations. Documented responses to the recommendations of the visiting team are required at interim intervals.

MSSA Board of Trustees
With 11 members from a variety of professional backgrounds, but all with a common passion for MSSA and Montessori education, MSSA Board of Trustees meets regularly with Head of School Emily Lund and MSSA Business Manager, Brandon Petrosky. The primary work of the Board of Trustees is to ensure and protect the long-term welfare and interest of the school and its mission. Each Trustee holds office for one or two three-year terms, not to exceed six years. Specific committees outlined in the Board By-Laws allow members to focus on specific objectives. These committees include: Executive Committee, Finance Committee, Institutional Advancement Committee, Committee on Trustees and other committees created as needed (Security, Policy Review, Building, etc.). Board members include ten current parents—with 16 current students and one alumni parent—with two MSSA graduates.
To ensure the institution remains financially strong for our children’s children and to preserve and actively support the school in the realization of its mission.
