I'm an IB trained teacher. There are several schools in QLD..public schools that have adopted the IB program too.
I was trained at my last school and it was going through accreditation for it.
Honestly, the pedagogy isn't too dissimilar to any enquiry based learning and most schools teach in a way that does this these days, as it's been the current trend in education. Doesn't have to be an IB school to be teaching enquiry based.
