I have a language school in an isolated part of Spain. We run Trinity College London oral exams for students learning English as a Foreign Language.
I like the system, and the Spanish staff give me a great service. One of our "selling points " is that these exams are well know the world over, and recognised in the academic and employment worlds. ( As opposed to Spanish language exams which are only recognised in Spain.)
To be honest, it's not really the case that they are widely recognised here. They are not well known to employers where I am , in fact very few people have heard of them.
I wondered if you have heard of them in your part of the world ?
