Advanced qualification for misguided sad gits who want to make a "career" out of teaching English.

Diploma in English Language Teaching to Adults. Advanced teaching qualification validated by Cambridge University.

DELTA, the Diploma in English Language Teaching to Adults, is a professional qualification in English language teaching awarded by Cambridge Assessment, formerly UCLES, a part of the University of Cambridge. The Diploma (or Dip) is often seen as a follow-up to the certificate known as the CELTA, once the individual has done a couple of years of teaching and has decided on a more long-term and serious commitment to the teaching of English. The Dip does not cover related non-teaching responsibilities (admininstration, training of teachers, and so on), but those who undertake these tasks often hold this qualification, or its equivalent.
