I did the Trinity CertTESOL course in 2010 at OxfordTEFL (in Barcelona) and I am very happy to have done so. Everyone is super friendly and supportive and all the work I had to do before moving there was very swift due to the help I got from them. The course is very complete and it’s probably one of the best decisions I’ve made in my life! They helped me find a job less than a month after I was done with the course (and I’m a non-EU memeber) and I’m still here in BCN! I’d recommend the course to anyone, experienced in TEFL or not.
* I even met my boyfriend (who’s a keeper!) through a friend from the course! hehehe =)
