Wellington College Bangkok: ASEAN's first campus, built from scratch in 2018
Founded in 2018 on a purpose-built campus in eastern Bangkok, Wellington College International School Bangkok became the first COBIS-accredited school in history to earn that status within its opening year.
Wellington College International School Bangkok opened its gates in August 2018, becoming the first Wellington College campus in ASEAN. The project had been years in the making. Dr Darika Lathapipat, Chancellor of Dhurakij Pundit University, and Gurdist Chansrichawla, a Thai senator and member of the Senate Economic Finance and Banking Standing Committee, secured the licence from Wellington College Education and established the school under Thai Education Holdings. Symphony Asia Holdings joined as an investor. The total build cost stood at 2.5 billion baht.
The founding logic was straightforward. Dr Lathapipat, who holds degrees from Imperial College London and a doctorate from the University of New South Wales, had identified a gap at the premium end of Bangkok's international school market. Wellington College Education, the master licensor based in the UK, agreed that Thailand was ready. The Eastern Economic Corridor development nearby, linking Chon Buri, Rayong and Chachoengsao to the capital, added commercial weight to the case.
Origins and Opening
The school opened on Krungthep Kreetha Road in the Saphan Sung district of eastern Bangkok, roughly midway between the city centre and Suvarnabhumi Airport. The site spans 70 rai, or 28 acres. Phase one delivered the Junior School building and full sports facilities; the school admitted students from Pre-Nursery through Year 6 at launch, with senior years to follow.
Chris Nicholls was appointed Founding Master before the school opened. He had begun his teaching career at Caterham School in the UK, then worked at Tanglin Trust School in Singapore, led Senior School development at the British School in Tokyo, and spent two years establishing a new school in Warsaw before joining Wellington in 2017. He remains Master today.
Heritage
The founding school in Berkshire dates to 1856, when Queen Victoria established it in memory of Arthur Wellesley, the Duke of Wellington. The college admitted its first 76 students on 20 January 1859. Wellington College International, the dedicated international arm of Wellington College Education, was established in 2009 to license the brand and its pedagogy to selected partners worldwide. Bangkok was the network's fifth international addition and its first in Southeast Asia.
Accreditation and Recognition
Within its first year of operation, the school earned full COBIS Patron's Accreditation from the Council of British International Schools, a record: no school anywhere had achieved that status so quickly. In January 2024, the Council of International Schools awarded CIS accreditation, recognising the school's continuing commitment to international education standards. The school was also shortlisted for the British International School of the Year Award in 2022.
Campus Growth
The original campus plan was always phased. Phase one covered the Pre-Prep and Prep building with full sports facilities. Phase two was the bespoke Senior School. The six-storey Skylight Building, featuring a cylindrical library and central atrium designed to flood the school with natural light, opened in 2021. It houses Harkness classrooms built specifically for discussion-based learning, science laboratories, music rooms, a dining terrace and a health centre. A second senior building, The Crowthorne, followed in August 2025, bringing the Senior School's total capacity to around 800 students across both structures. The Sixth Form, offering A Levels in Years 12 and 13, launched in August 2024.
Sports infrastructure across the campus includes a 50-metre Olympic-length pool, a 25-metre training pool, a 400-metre athletics track, a 600-seat theatre, a golf simulator and short-course golf area, four tennis and multi-purpose courts, and a sports hall containing a dance studio, gym and gymnastics room.
Curriculum and Identity
The school follows the English National Curriculum from Pre-Nursery through the Junior years, leads students to Cambridge IGCSE in Years 10 and 11, and delivers A Levels in the Sixth Form. The curriculum sits firmly in the British independent-school tradition rather than the IB pathway. Mandarin, French and Spanish run alongside English as the primary language of instruction. The school frames its pastoral and academic culture around five values it calls the five Is: Inspired, Intellectual, Independent, Individual and Inclusive, a framework carried from Wellington College Berkshire into all its international schools.
Pedagogically, the school places particular emphasis on Harkness learning, a discussion-based method imported from elite American prep schools and championed by former Wellington Master Sir Anthony Seldon, alongside wellbeing as a structured element of school life. The school participates in Summer School programmes at the Berkshire campus and student exchanges across the Wellington family, which now includes schools in China, India and Indonesia as well as Thailand.
Present Day
The school currently enrols around 1,100 students from Pre-Nursery through Year 13. The student body is predominantly Thai, with roughly 75 percent holding Thai passports, alongside an expatriate cohort drawn by the school's British independent-school culture and its position at the premium end of the Bangkok market. Christopher Nicholls continues as Master. The campus operates at 18 Krungthep Kreetha Road, Thap Chang, Saphan Sung, with a designed capacity of 1,500 students once all phases are fully occupied.
