Great. Also IBacc? Then substitute teaching may be a good way in for you. Not a lot of posts seem to come up but a friend of mine worked there - still might tbh, not spoken for a while - and AFAIK likes it.

Edit: you're in luck - they need a part time Spanish teacher and are accepting applications for substitute teachers.

ok, I created an account just for this. I had children who went to ISB (one also went to SIS) I thought before there was something not right about these messages.
I have learned indirectly that they were posted by one person who was sacked. My children never had any problem and as far as I know it is still a very good school.

Changes were made. Some people didn't like it and made a lot of noise for a while, attempting to use social media to make it seem like they were representative. Meanwhile, the world kept turning.

I know of good things that are done at ISB, and some rather bad things. Nothing is perfect.
