PGCE 100%!!
I have just returned to England to complete a PGCE because the truth of the mater is, TEFL is a crap industry, with crap employers, crap pay, and mickey mouse private companies!
Do the PGCE, get avery well paid job in an inetrantional school anywhere in the world(after 1 year experience in an English school)..
I was earning around $1000 a month in Indonesia working for EF a private language centre, but my friend was working just 10 mins from me in an international school earning around $4000 a month and enjoying a job with career prospects, great benefits, all expenses paid acccom, flights, pension.etc.
We both enjoyed our jobs, loved the life in the country, but he was getting a much better deal than me, because of the PGCE.
+ he was looked at as a professional, where as the TEFL Industry treats its workers as if they are just back packers looking for beer money(which most are to be honest).
Do a nother year, get your PGCE, and you can enjoy the TEFL lifestyle in style!
