TSI, formerly known as Thai Sikh International School, has operated since 1985 and now runs two campuses, including its main Bearing site near Bearing BTS station in Samut Prakan, serving students from Pre-Nursery through Year 13 across its full continuum.
The school's original name and founding reflect roots in Bangkok's Sikh community, though it has broadened its identity and enrollment considerably since 1985 under its current TSI branding, similar to how several other Bangkok schools have evolved their public identity over time while retaining their founding institutional base.
With four decades of operating history and a full Pre-Nursery through Year 13 continuum across two campuses, TSI offers families a genuinely long-established, single-network option without needing to transition between separate primary and secondary schools.
Families researching TSI should confirm which of the two campuses they are considering, since facilities and exact program details can differ between the main Bearing site and the school's second location.
