I think it comes back to leadership. Where we have very strong strategic leadership in schools, they are more direct in their approach, and they have a very strong strategy. Where there's weaker leadership, sometimes they are trying different things, perhaps in more of a scattergun approach, rather than trying strategies, evaluating and finding out what works. There is an element of the impact of leadership there.
Okay.
Okay, Hefin? Okay.
I think it is true to say that it's difficult to distinguish what some of these better schools do with PDG, as opposed to their general money. If that's what you're getting at, I would totally agree. Schools like Cefn Hengoed will be using more than just the PDG to do this work.
