Hello,

Yes, the nZ PhysioBoard does require you to prove your english language skills.
IELTS with an avarage of no lower that 7.5 and no score under 7 or TOEFL (and I'm not sure of th escore. IELTS has a website you can google and there you can find a lot of information on the test. It gives you options for traiing and that is well worth it! PLease do those training things cause it will make it very clear what to write in the writing test, for example.
Good luck, you can do it!!!!!!

Kind Regards, Lien
