An English teacher has told ITV News that Ofqual's report was the "latest in a category of insults against teachers".
Chris Edwards, who wrote an open letter to Education Secretary Michael Gove in September criticising the decline of A* to C GCSE grades, said:
I'd like to say I'm shocked and surprised by this report but it's the latest in a category of insults against teachers.
You can imagine how demoralising this is for youngsters, they've got to resit exams on Wednesday and you can imagine how difficult it is to sit an exam you've already taken.
Ofqual don't seem to make any reference as to what they will do about this situation and they've turned the blame on the teachers which is unbelievable.
Asked whether teachers were under pressure to secure good grades, Mr Edwards said:
Most teachers thrive on that pressure but it doesn't help that every time results go up it's down to exams getting easier.
