International Baccalaureate Schools?

[PNGMK]

A lot of International Schools offer it - some well, mostly not that well.

Joins ISS or similar to find a job (they run job fairs etc) or peruse the career sections of schools that interest you. You're a bit late for this academic year and but about right for the 2015/2016 year recruiting.

I am a psychology teacher and am interested in teaching IB psychology in Singapore. How popular is the IB program in Singapore? Would I have any trouble finding a job?

You can consider International Schools for a better future for you. The kind of exposure you get in the school is way ahead of its time.
