My bf applied to HKU at the start of the year to do the PGDE, but the woman running the course seemed really anti-expats on the course and trying to put ppl off from doing it! I think they are aiming to improve locals role as english teachers rather than for foreigners to gain a cert. It was quite a headache, just the applying process.
Also, the HK PGDE is not totally recognised internationally, as someone mentioned, you would have to do a conversion course back in your own country to make you eligible to teach back home.
And a further point is you would have to pay international school fees here, which is sth like HK$90k?? I'm not sure if that is correct, but I think we saw that figure and were put off.
Anyway, so my bf applied to do the PGCE back in UK, where tuition is paid and he gets a grant, then he will come back.
