And their comprehension as well.
Absolutely, yes—those higher level skills of comprehension and inference and those sorts of things.
Sure, okay. Can I just move you on, then, to numeracy and whether you can tell us if you're satisfied with the progress in numeracy, because I think we were doing better on the PISA results in maths in Wales than we did previously? So, what are your thoughts on that?
I think there is a fairly clear good news story here. PISA shows improvements and a lot of that can be attributed, I think, to the new GCSE mathematics numeracy. I think there's much less predictability in that work; you can't approach it in a formulaic way, either the pupils or the teachers in terms of teaching it. There's much more problem solving. It's about applying what you've learnt in the core mathematics lessons to new situations in subjects across the curriculum. I think that that GCSE numeracy has built on the work that's been done lower down on the national numeracy framework, which has the same philosophy of applying that mathematics knowledge in a problem-solving situation. That has been a really good news story, really.
