Speaking from experience as a recently retired Headteacher, whose main teaching subjects were History and Politics, Paul is (sadly, I believe) more accurate in today’s climate.
Recent governments, particularly since 2016, have pushed a more uncritical approach to British history, particularly in the more imperial sense. Moderators please note, this is statement of fact and can be verified via DfE documentation. I am not giving a view.
There is flexibility to an extent, particularly in younger stages, where elements of African history and American First Nations history are still able to be squeezed in, but most exam-focussed history tends to be British, although one is still able to cover topics such as the Cold War as an international area, albeit with a bigger emphasis on the European aspects. Germany 1919-33 is also available.
Sadly, International GCSEs were abolished in 2018.
It is still possible to teach the International Baccalaureate (IB) in all subjects. An excellent qualification, if somewhat bureaucratic in administration, particularly in History and ( my personal favourite to teach) Global Politics.
Not trying to contradict anyone, but since the discussion was about my direct area of work, both as teacher and school leader, I thought I’d put my tuppence in.
