Q. How long are you planning on staying there?
We took ours out to Munich for 3 years but, as it was always going to be a temporary thing, we timed it so that the eldest would be back in the UK system before starting high school. My company paid for them to attend an international school. Who’s going to be paying? It’s not cheap.
Check what qualifications are being offered, IB or IGCSE.
If IB, then you’d want to consider how well that would transfer back into the UK if you were to return mid-course.
We generally found the lower school to lag behind the UK accademically but the experience gained of mixing with a wide range of kids was a valuable experience in itself.
If you are going to move permenantly, it’s a whole different ballgame and you should be considering how best to get them into the mainstream German system.
My experience is about ten years old though now. Not current, so much may have changed since then.
