As I say, the national indicators were supplemented by the School Health Research Network data in the final framework. So, I think there were a number of considerations here. One was, if you like, a non-binding consideration, in that the national indicators formed part of the brief and a central part of the work. We did include, and considered including, some wider data. And, in fact, I think in no small part that SHRN data was included because, at the interim review, I expressed a concern that a number of the indicators were relating to childhood in its oldest years—so, for children aged 16 and over. And I suppose I was concerned about balance there, and for the need to try and include some child indicators that would capture childhood in its earlier stages. And the SHRN data was included in part because those indicators are deemed significant, but also in part to try and overcome an initial perception of imbalance in terms of the indicators.
The other thing to say is that there were other considerations. No. 1 is we need data that are robust, and I'm not suggesting that that excludes everything else, but it does exclude some things. You can consider such and such an indicator—it might sound like a plausible indicator, but if it's not collected through a robust mechanism, then that would be potentially a very significant risk if the Welsh Government were to start monitoring its performance on an indicator that there wasn't robust data on, and there was one of the team of officials who was very attuned to that concern and was able to come back, and say, 'Actually, we don't have data that we can trust on this indicator'.
The other concern was that we also need indicators that reflect outcomes themselves and not policy initiatives. And I think that was actually an issue that we had with respect, I think, to the homeless data. One of the issues there was that I think we looked at a number of potential indicators and couldn't arrive at a formulation that would separate out the outcome of homelessness from the policy effort of the Welsh Government, because I think what you want to avoid is a scenario where the Welsh Government do more, which is a good thing, but that good thing is being interpreted as a deteriorating outcome because more is being done. You mentioned access to hospitals—and I don't question that you can formulate an indicator that might work in relation to that—but if, for example, doctors see more children, that could be interpreted as a sign that children are getting less healthy, but it might also just be a sign that GPs or doctors are getting to see more children, which is a good thing. So, some of the indicators, there wasn't robust data; some of the indicators, it was a struggle to formulate them in a way that was satisfactory.
One of my roles, as I say, has been to try and step back and provide an overview. And early on, I tried to established a principles-based approach for my own consideration of these indicators, because one of my concerns is that the framework as a whole would be relatively consistent, and it wouldn't be a jumble of indicators measuring entirely different things and in entirely different ways, which I think would be an issue. The first principle I outlined in my review was that the indicators should have a clear and accepted normative interpretation, and being able to separate out that policy effect from the social outcome is really central to that. It's very important if something is going up, and you're viewing that as a problem, that it's the incidence of the problem that's increasing and not the incidence of the policy effort or effect of the Welsh Government, because then you're confusing policy from outcome. And that's a principle that Tony Atkinson and colleagues advocated to the European Commission, and forms the basis of the European Commission's monitoring frameworks, and I think it's a really important one.
