There are at least 5 big name schools opening in BKK this year (or opened late last year), they are joining an already crowded market with some excellent well established schools. They're not opening because expat workers can't find IS places for their kids, they're opening because many Thais will leave the state education system as soon as they can afford to. The schools are spotting an opportunity with a potentially growing middle class. Therefore there a couple of considerations: (i) these new int schools will have mainly Thai students, this is not a bad thing (imo Thai students are lovely to teach), it's just that the schools may not feel like a more typical international school. Most expats already have their kids at the established schools, and most newly arriving expats will probably opt for the established schools for the next few years (big assumption, I know). (ii) the success of these new schools is obviously dependent on the Thai middle class continuing to grow. There are obviously Covid related economic worries in Thailand as there are everywhere, however beyond Covid there are additional local issues that might give cause for concern about the mid-term stability of the economy, and specifically about the distribution of wealth in the middle classes. Those in Thailand will have a sense of some of these issues.
