If you read the original article linked in post #1 it never said Ofsted would penalise schools - the thread title should have had a '?' at the end of it really. It was a bit of kite-flying by ASCL when the current Ofsted Framework was being consulted on at the beginning of this year. The actual Handbook from this term does comment on the issue but does not say it will be penalised per se [Ofsted Inspection Handbook September 2019 - 'Curriculum narrowing' - paras 176 & 177]. So I doubt any school has been penalised solely because they have 3 year GCSE courses.
