Established in 2010, Montessori Academy Bangkok International School (MABIS) is the leading trilingual Montessori school in Bangkok offering Toddler through Secondary programs. We are committed to a high-quality Montessori program. MABIS has a beautiful campus, purpose-built classrooms and facilities. Learning is localized and customized through extensive field explorations. We are also the only WASC accredited Montessori school outside of the United States. The Montessori Secondary program for students ages 12-18 (US Grades 7-12) is a dynamic learning environment where adolescents perform meaningful work that simulates experiences in the adult world. Students pursue projects that serve their interests and the community, allowing them to deepen their sense of self as they identify strengths, passions and unique capacities. Students will also have the option to pursue the IB Diploma during their final two years of the program.
