A south London school has accused Ofsted inspectors of being ''rude and dismissive'' and making up evidence.
Battersea Park School complained in June about the conduct of inspectors after they received a critical report, which said "teaching was inadequate" and that "students did not do well enough".
A few months later the school saw a 14% rise in pupils gaining five A to C grades.
The watchdog said claims the findings in the inspection were not based on evidence were "totally unfounded".
It said all complaints were investigated "thoroughly and rigorously".
Parent Barrie Morgan says the perception is that it is a good school while education expert Chris Waterman says inspections have high stakes as teachers can lose their jobs over them.
