I really wouldn't waste your time with the likes of Silverboy. What he knows about teaching can be written on the back of a very small beer mat and most likely has been in the past! He believes a 5 minute, self written and administered oral exam is better than a CAE speaking exam to test a student's fluency... I really wish I was making that up but unfortunately I'm not.

Has there been any developments about this situation? I work for Cambridge ESOL as an examiner and I have spoken to my team leader about the issues you posted originally. There's not much we can do personally as we're based in Spain, but you should get in touch with the CESOL department for China accreditation. They will listen to your accounts and get an inspector out there.
