maths, two english, three sciences, a MFL, history or geography, RE and one or two other choices
Goodbye, that is exactly what I mean by narrowing the curriculum.
By comparison, very able DD and all her classmates in a good comp with a 3 year KS3 studied in Y9:
Maths, English, 3 sciences, History and Geography and RE, 2 MFLs (or 1 MFL + SEN support), 3 blocks of different DT subjects, Art, Drama, Music, Computing (as in coding, not 'use of computers') and obviously PE.
Yes, DD then narrowed down to what you describe in Y10 (no RE, but 2 MFL, 1 creative and 1 DT subject) - but it was the preservation of a broad curriculum for all in Y9, whether their final destinations are more or less academic, which I see as important where a good proportion will have no exposure to e.g. drama, music, 'general knowledge' of history, geography etc outside school.
On the 'GCSE guidance by schools', I agree with howabout that this is in fact a FAR more difficult challenge for less academic pupils. I have always admired whoever put together the option blocks for DC's school - the black art of looking entirely flexible while in fact subtly channelling pupils of every ability into sensible GCSE combinations!
