In brief
Two schools in this guide describe Montessori methods in their early years: Kids Avenue in Si Racha and Mooltripakdee (MIS) in Pattaya. Both describe their approach themselves; it is not evidence of Montessori accreditation. MIS’s published 2026/27 tuition was rechecked on 23 October 2026; Kids Avenue fees remain on request.
Fees are yearly tuition from each school’s own fee page; extras such as entry fees, bus and meals are on each profile. Compare these fees grade by grade.
We found none in this guide with a Montessori accreditation we could confirm. Kids Avenue describes a Montessori-inspired early-years approach and Mooltripakdee lists Montessori methodology for its early years. Ask each school whether its teachers hold Montessori training and from which body.
Kids Avenue advertises ages 1.5 to 6. Mooltripakdee’s Montessori approach is in its early years, before it moves to the British curriculum through to A Level.
Kids Avenue supplies its fees on request. MIS’s 2026/27 tuition is ฿210,000–฿265,500 across its Preschool and Kindergarten bands, with compulsory supplementary fees additional. The fee page was rechecked on 23 October 2026; confirm the correct attendance pattern and first-year total.
