Teaching Qualifications

English language teaching qualifications with IH London: CELTA and Delta 

With so many acronyms – CELTA, Delta, TESOL, TEFL – it’s sometimes hard to know which English language teaching qualification is right for you.

At IH London, we train teachers with Cambridge English qualifications: CELTA and Delta. Cambridge English is part of the University of Cambridge.

Our experts think the Cambridge English CELTA and Delta are the best qualifications for teachers. They are comprehensive courses that cover everything a teacher needs to know at the relevant level, they are recognised across the globe, and they are the qualifications asked for by good quality schools.
