I recently completed the Business English Teacher Development course through Oxford TEFL after having had a really positive experience completing my CELTA certification through them, too. The Business English course was very comprehensive, covering all the relevant topics required to be an effective instructor. The course was conducted on a one-to-one basis and my instructor replied to any queries or problems I had in an efficient and comprehensive manner. I also valued the contact sessions where we explored the tasks and assignments and I was able to ask any questions relating to the course. This is a great course for anyone looking to develop their Business English teaching skills and knowledge.
