Heathfield International School Bangkok Joins ISP in Latest Thailand Deal
International Schools Partnership has acquired a 400-student British-curriculum school in Bangkok, bringing its Thai network to four campuses as operator consolidation runs alongside a wave of new openings.
International Schools Partnership has acquired Heathfield International School of Bangkok, according to EducationInvestor Global, in a deal announced on 22 June that adds a fourth Thai campus to the group's 119-school global network. Heathfield, established in 2007 in the Saphan Sung district of east Bangkok, serves around 400 students aged two to 18 on a British curriculum with a strong emphasis on arts, music, and sport.
The school occupies a suburban site with spacious outdoor facilities, a profile that sits in contrast to the more central Bangkok locations favoured by several of the premium brands opening in the city this year. Its fee schedule is pitched at the mid-market, serving a mix of locally based international families and Bangkok residents seeking a British education without the top-tier price point.
ISP's model at Heathfield
ISP will apply its Learning.First approach, an evidence-led teaching framework developed centrally and deployed across the group's global portfolio. The group typically retains existing school leadership in the early months after an acquisition, phasing in network professional development and shared operational resources through the first academic year. For Heathfield, that means access to group procurement, legal infrastructure, and cross-marketing to internationally mobile families already enrolled at ISP schools elsewhere in Asia and further afield.
Why Bangkok, why now
ISP's move comes at an unusual moment in Bangkok's international school market. The 2026-27 academic year has seen a concentration of brand-name openings, with Dulwich College, Wycombe Abbey, Highgate, St Paul's Girls' School, and Glenalmond all launching debut Thai campuses between August and September. Premium new supply at the top end of the fee spectrum raises natural questions about demand displacement in the mid-market where Heathfield operates.
The acquisition suggests ISP views group scale as a structural advantage in markets facing new competition, rather than a reason to pause. The global operators that have made Bangkok a priority for 2026-27, among them Nord Anglia with its existing presence and ISP with its expanding one, are betting that ownership across a city's fee tiers provides insulation from volatility in any single segment. For Heathfield's students and staff, the immediate practical effect is joining a network whose professional development and curriculum resources far exceed what an independently operated 400-pupil school can typically sustain.
