A union leader said the on-air sacking of an American headteacher was the "ultimate humiliation".
The ATL's Mary Bousted tackled Michelle Rhee, who used to run Washington schools, on her dismissal of a head teacher which was shown in a TV programme.
The pair debated American lessons for UK schools, claims of cheating in the US system, and how under-performing teachers were removed in Britain.
