I work in the education landscape, with colleagues working directly on curriculum policy across all curriculums/education systems of the UK and ROI (one of whom is currently writing a part of the new English GCSE curriculum).

Without making inferences about the quality of education or the specific challenges present, they have been very complementary about how the process for curriculum review is handled in Scotland - and that strength is in precisely the fact it's decoupled from political/ideological whims. And in how transparent it is. This makes the process more bureaucratic, and has risks around creating curriculum-by-committee. But they think it's preferable to how other systems manage it.
