Hi,
well, the criteria for NZ registration are not negotionable. And that's it. We all have to go through the same process. Yes, total easy for Scottish and Irish and easy for British, mainly because their Physio programmes are very similar to the programme over here. However,...
I worked in a large Physio team last year, including non-English-first-language speakers from Sweden, Germany, Zimbabwe, India, Spain and Columbia.
They all got at least 7.5 in their IELTS.
There is training materials, books, tapes etc.. You can sometimes even get them second hand. Or you might need to do a IELTS training course.
I believe, it is quite reasonable to set high standards. But that's just me.
regards,
Fyzzio
