In Brief
Lertlah School is a Bangkok international school with multiple campuses that appears to serve as a stepping stone for new teachers seeking Thailand experience. While the school offers a Canadian curriculum partnership and has been operating for over 20 years, it maintains an extremely low profile in Bangkok's competitive international education market.
Established with over 20 years of experience, Lertlah operates multiple campuses including locations at Campus 1, Campus 2, and Campus 3. Recent teacher discussions reveal the school partners with a Canadian curriculum provider, though specific details about academic programs, year groups served, or qualifications offered remain unclear. The school appears to recruit heavily through short-term contracts, offering May-July positions and May-February contracts to new teachers, with orientation periods varying based on contract start dates.
Teacher perspectives consistently describe Lertlah as suitable for gaining initial Bangkok teaching experience rather than a long-term career destination. The school accommodates specific teacher needs including pet relocation for small breeds, suggesting flexible policies for expatriate staff. However, unlike Bangkok's established tier-one institutions such as ISB, NIST, or Bangkok Patana that generate extensive parent forum discussions and detailed reviews, Lertlah operates with minimal visibility in international education conversations, suggesting it serves a localized market rather than competing for expatriate families.
