"In England, by law children are to be taught about the Holocaust as part of the Key Stage 3 History curriculum; in fact, the Holocaust is the only historical event whose study is compulsory on the National Curriculum. This usually occurs in Year 9 (age 13-14)."

So not Province of Northern Ireland, Scotland or Wales. Note that WW2 is not a statutory requirement in any of the key stages although it does feature in the examples (which are non-statutory). And a reminder that history is a required subject only to Key Stage 3, so many students won't take it after they are 14 and won't study for an exam.

Reporting on education in the UK does tend to be rage-baity and most situations are more complex when you look at them a bit closer.

(I have never taught history and never taught in the school sector)
