text: I have worked with teachers who have done the Global course and the LTTC courses and they both have similar approaches to their work but neither opted for the full practical option as part of their respective courses.\nThe Cambridge CELTA and the Trinity College (London) TESOL are certainly the most widely known in Europe and elsewhere. It does depend on where you are thinking of teaching next and if you intend to make English teaching your career, at least for a few years.
