Principal's Message

Empowering students for success in a global and evolving world.
Welcome to the American School of Ulaanbaatar Secondary School for the 2025–2026 academic year. We are excited to welcome both new and returning families into our vibrant and supportive learning community.

At ASU, we are committed to building on the strong academic and personal foundations developed in Elementary School. Our goal is to nurture students who are confident, responsible, and engaged learners, with a strong sense of identity and belonging. Through a balanced focus on academic excellence and social-emotional development, we prepare students to navigate an increasingly complex and interconnected world.

Guided by our motto, “Home of Future Leaders,” we strive to empower students not only to succeed globally but also to make meaningful contributions to Mongolia as innovative and compassionate leaders.

Our dedicated faculty and staff are deeply committed to each student’s growth, well-being, and success. We value our partnership with families and appreciate your continued trust and support.

We look forward to a successful and inspiring year together.
