Thailand's International Schools Keep Growing as the Economy Cools
A decade of rapid expansion shows no signs of reversing, even as Thai economic growth slows and falling birth rates raise longer-term questions about the size of the student pool.
Thailand's international school sector is still expanding, with the number of schools approaching 300 and student enrolment having nearly doubled since 2014, even as the country faces some of its most difficult economic conditions in years. According to The Nation Thailand, the growth is now being driven primarily by wealthy Thai families and highly skilled foreign workers rather than the traditional expatriate market, insulating the sector from the general deterioration in economic sentiment.
Thailand's economy is forecast to grow by only 1.5 to 1.8 percent in 2026, held back by U.S. trade tariffs, a global slowdown and a strong baht weighing on exports and tourism. Yet international school operators have continued investing. Wells International School, one of the sector's more visible domestic chains, is actively preparing for a public offering, with a target of mid-2026 or the following year at the latest.
Who is driving demand
The sector's resilience tracks closely with wealth demographics rather than headline economic conditions. The number of Thais with assets exceeding USD 1 million is forecast to reach around 162,000 in 2026, growing at an average of 11.7 percent annually and concentrated in Bangkok and major business cities. That pool of affluent local families is now the primary demand driver at most Bangkok international schools, having displaced the corporate expat packages that historically filled places.
Alongside them, highly skilled foreign workers have been growing at an average of 9.3 percent annually since 2020, with 13.4 percent growth recorded in 2025 alone. Executives and specialists in finance, technology and services represent a consistent and resilient source of enrolment that is less sensitive to Thailand's headline economic performance than consumer spending in general.
The shadow of demography
The longer-term picture is more complicated. Thailand's fertility rate has been declining for years, and private school closures have accelerated: nearly 10 percent of private schools shut last year. International schools have so far been shielded from those pressures because they draw from a narrower and more financially resilient slice of the population. But the shrinking pool of school-age children will eventually arrive as a constraint, regardless of how affluent the parents are.
For operators already established in Bangkok and major Thai cities, the practical implication is to build market share now rather than later. For new entrants still weighing whether to commit capital to the market, the demographic question is the first hard item on any serious due diligence list.
