Why no single sex or selective International Schools?

[Curious Cat]

Hi

Just taking a look at what's on offer. We were looking ideally for a boys school, just curious why there are no single sex or selective International schools here?

Are they against the local laws?

[only local]

There are plenty of single sex local schools, but none that I know of as international schools, but there's nothing to stop you applying for a local school.

I assume there are no international schools which go down this route simply because nobody has ever thought to open one, as far as I know, there are no laws against it (there can't be if there are single sex local schools).

[demand?]

I imagine there has never been enough demand for such schools in the international community for anyone to venture out and open one. Setting up a new school here is very expensive; so maybe the pool of parents that would consider it for their children just doesn't justify the effort? I know single-sex schools from having lived in Britain, but in many European countries they don't exist and would go against a lot of people's outlook. I'm not against them myself; just can't see them succeed in such a small place.
