Wells Thong Lo is the kindergarten campus of the Wells network, serving children from Nursery through Grade 2 (ages 2 to 8), with the natural onward progression to the On Nut campus for Grade 1 and beyond.
Part of EverClever Education Group and following the same American curriculum as the wider Wells system, the campus has a warm, small-school feel that suits the early years well. Class sizes are small, the community is genuinely international, and the location is one of the most practical of any kindergarten in Bangkok: Sukhumvit Soi 51 in Watthana, a short walk from Thong Lo BTS.
For families living in the Thong Lo, Ekkamai, or Phrom Phong corridor, this removes the commute problem entirely for the early years. Fees sit at the accessible end of the Bangkok international kindergarten range. One thing to plan before enrolment: the Thong Lo campus stops at Grade 2. Families who want to continue in the Wells system will move their child to the On Nut campus for Grade 1 or Grade 3, so it is worth familiarising yourself with that campus and its location at the same time as applying here.

What You Should Actually Know About Wells International School - Thong Lo
Wells International School - Thong Lo is the founding campus of the EverClever Education Group, operating on Sukhumvit Soi 51 in Bangkok's Wattana district since 2003 after the group's original kindergarten at Soi 47 outgrew its premises. The Thong Lo campus serves children from Nursery through Grade 3, making it a pure early years and lower primary school rather than a full K-12 institution.
Its American-based curriculum is modified to meet Thai Ministry of Education requirements and is delivered entirely in English, with Thai taught as a compulsory subject throughout. The campus is accredited by the Western Association of Schools and Colleges (WASC) and holds ONESQA recognition, the same credentials as the group's flagship On Nut campus.
What defines Thong Lo in practice is scale and intimacy: the campus was designed specifically for young learners aged 2 to 8, built around a central covered playground, with low steps, child-size bathrooms, and age-appropriate furniture throughout. The student body represents more than 15 nationalities, with Korean, Japanese, Thai, and Indian families forming significant communities.
The school draws heavily from the surrounding Thong Lo and Phrom Phong residential area, and the walking distance from Thong Lo BTS station makes it one of the more transit-accessible kindergartens in upper Sukhumvit. Teaching staff include specialists for music, dance, art, PE, and computer skills, alongside homeroom teachers and classroom assistants. Classrooms are equipped with computers connected to projectors or wide-screen televisions, integrating technology into daily lessons from the earliest years.
ESL support is available as an add-on service for students who are not yet proficient in English, priced separately per semester. For families considering the full Wells pathway, Thong Lo students typically transition to either the On Nut campus (Grades 1-12) or the Bang Na campus (Nursery-Grade 5) for primary and secondary education. Thong Lo itself does not offer secondary schooling, AP courses, or the IB Diploma, so families intending to stay within the Wells system need to plan for a campus change at or before Grade 4. The school is best suited to expatriate and mixed-nationality families with young children living within easy reach of the Thong Lo-Phrom Phong corridor who value a friendly, community-oriented early years programme at a fee level that sits below the mid-range of Bangkok international schooling.
