It is shocking.
So, that's our main source of information. Does that answer your question?
Yes, but how will any gaps in your data be addressed?
Well, one of the questions that are often asked is: could we measure more on a longitudinal basis? By that I mean in England, for example, children are measured at school entry and then again at year 11—at age 11 or 12., that kind of age group. And so you do have a longitudinal view over time of what's happening to children. I think that would be helpful to us in Wales, and it's one of the questions in the consultation about whether we should expand that. Obviously, that would have significant resource implications, not just for the funding, but also for schools and for the system to deliver it. But it's something that maybe would help us in terms of better understanding and better evaluation—the point that was made earlier.
