Chris Edwards wrote: "They can't understand why someone would want to play around with their futures in such a cruel way and we, as teachers, should not have to be the ones to explain it to them.
"You have not simply moved the goalposts. You have demolished them, sold off the playing fields where they once stood and left the dreams of these youngsters in tatters."
Ofqual denied applying pressure to exam boards to change their grades, saying it was merely playing its proper role in regulating standards.
Schools alliance have announced they have formed an alliance to demand an independent inquiry into the GCSE English grading fiasco.
Exams regulator, Ofqual is to look again at some GCSE English results amid claims that thousands of students have been treated unfairly.
