The teflblacklist in an inactive blog which listed schools which teachers had found to be problematic.
Its last post is dated December 03, 2008, though its history still exists and makes for interesting reading.
Even a casual glance through the postings will suggest issues which potential teachers should be aware of, as the market is full of cowboy outfits, and even famous schools are not beyond a little creative accounting.
It was run by the blogger and teacher Sandy McManus who now carries out some similar reporting at The TEFL Tradesman.
The views expressed on Teflblacklist are not necessarily the views of Teflpedians.
