Nope, not exactly true imo.

'Deechers' can be found 'deeching' in all kinds of educational establishments. However, though there is no doubt that that scourge of EFL teaching is most prevalent at training centers, it also affects kindergartens, private schools and universities, and state-run educational establishments. Private schools and kindergartens have the most 'deechers' after training centers. There are also 'deechers' working in significant numbers for elementary schools, junior high schools, second-rate senior hign schools, and lowly colleges and universities, whose students are quite easily duped.

My definition/suggested meaning of a 'deecher' is a phoney teacher - one who's unqualified and/or unable to teach adequately due to a bad accent or a low level of the English language.

'Deecher' is a word invented by Turnoi. It might well have a different meaning in his eyes to my suggested meaning.

Double nope and no disrespect to Turnoi but I think 'deecher' came from 'beacher' and that was the name given to useless fake teachers about 15 years ago in my prime. These beachers were so bad that they felt it safer to never changed jobs and used to beach themselves (like whales) at one school for many years.

The fact remains that GWs are Turnoi's spin-off of Beachers, deechers. Cheers SM.
