Can I thank Hefin David for his questions and his kind comments? I think I've got the best job in the world, even in the middle of a global pandemic, so thank you for your kind words. It's always the kindness that kills you, isn't it, Deputy Presiding Officer? But thank you very much for that. 

In terms of moderation, the details of the moderation process is the main job of the design and delivery group. I'm not putting any constraints on that, except the broad principles about them being equitable and fair and building confidence. And we will look to have a verification of moderation processes, whether that be at a school based level or whether that be at a cluster based level, but we want a national verification that the school—the individual centre—has everything that they need in place to give confidence that their moderation processes are fair and robust. I'm mindful of workload, as always, in all of this, and, of course, the more we take teachers out into time to do these kinds of issues we're taking them away from being in front of their children and their students. But, clearly, that will be a consideration for the design and delivery group, but it's certainly something that should be considered carefully.
