DLTS International School is part of the Denla Group, the Thai education group behind Denla British School, but it takes a different route from its sister school: an inquiry-based International Baccalaureate pathway rather than the British curriculum. DLTS is an IB Candidate School, running the Primary Years Programme in Grades 1 to 5 and the Middle Years Programme in Grades 6 to 9, and candidate status is not the same as full authorisation, so families should ask the school where it stands in that process.
Language is the school's defining feature. DLTS aims for students to become trilingual in English, Thai and Chinese, which makes it a natural option for Thai and Thai-Chinese families who want strong Mandarin alongside an international programme, as well as expat families who want their children to keep real Thai.
The campus is on Nakhon In Road in Bang Kruai, on the western side of Nonthaburi, so it mainly suits families already living in Nonthaburi rather than those commuting from central Bangkok. The school covers Toddler and Early Years classes from 18 months, then PYP, MYP and a Pre-College stage for Grades 10 to 12.
Teaching leans on STEM, critical thinking and project-based learning. Tuition includes lunch, snacks, learning materials and accident insurance, while ESL support and special needs support are charged separately and assessed case by case.

ESL starts at 30,000 a term and both support fees are set case by case. The page heading says 2026-2027 but its summary still says 2025-2026, so confirm the year with the school.
