Chiang Mai Montessori International School (CMM) is an independent Thai-British school established in 2010, located south of Chiang Mai city. CMM offers a comprehensive Montessori curriculum for children aged 18 months to 12 years and is set to launch a Montessori Erdkinder program for ages 12 and up in 2025, making it the first of its kind in Thailand.

The school prides itself on being firmly rooted in Thai culture while providing an international education experience with English as the primary language of instruction. CMM follows the AMI Montessori framework, largely employing AMI-trained teachers, but also welcomes experienced Montessori educators from various backgrounds.

CMM features a spacious campus with well-equipped facilities, including bright classrooms, a nature center known as WOWS!, a FIFA-approved football field, an organic vegetable garden, and community recreational areas. The school emphasizes outdoor activity and sports, led by a professional footballer with Montessori coaching accreditation, to enhance student development and enjoyment of school.

Founded by Mrs. Nathasassi Waritatanadejcho (Khru Aer), CMM reflects her dedication to providing a nurturing educational environment, influenced by her own experiences as a child. Her commitment to the school continues as she engages with the community, fostering a culture of growth and exploration encapsulated in the school motto, ‘Freedom to Grow – Time to Explore!’

CMM aims to create a unique learning environment, valuing both education and local culture while making a positive impact on the community.
