hello i also had this problem i came from new zealand 6 months ago i was in the middle of my ncea so i enrolled with te kura and i and i am finishing off hopefully soon i also went around to international school unfortunately most of them had no idea what ncea was ...

at the moment i am in a independent school so i do not waste time i am still looking for an international school .
most of them don't teach well .
i think i might just finish my level 2 online ...

and by the way Qatar university have no idea what ncea is my brother who completed ncea 3 tried applying but they had so many difficulties understanding what it was but after a few months of struggle they accepted him in some low course ... oh and if your son is going to enter year 12 of British curriculum here they will most probably say no and that he will need to start from level 1 ..

hope this helps..
