The CELTA is better than the Trinity TESOL. Oxford TEFL, which is authorized to teach the Trinity course, falsely claims that both courses are "essentially the same and both are equally recognized."
This is not true! Although the British Council recognizes both, employers have come to realize that the CELTA better prepares the students to teach in real life scenarios while the Trinity Course at Oxford TEFL is done but eccentric artists that waste students time with nonrealistic methodologies such as teaching adults as if they were 5 year olds!
I took the Trinity with Oxford TEFl and it was a waste of both time and money. The CELTA is run by professionals that respect the students and give them more value for their money. Oxford TEFL's Trinity TESOl is more like an assembly line of students being rushed in and out.
