Well, you'll be aware that we are moving away from level 2 plus as a performance measure anyway because of the—
So, what performance measures will you use?
So, for the lack of sophistication around the level 2 plus, and for the unintended behaviours that that particular performance measure has driven within our schools. I'll be making a statement shortly to the Assembly around a new performance measure for schools. We were, at our most recent secondary heads conference, working with schools to develop that. What's important to me is that we have a more sophisticated model that looks at school performance for all children. What level 2 plus does is narrow, very much, the focus of schools on an individual part of the cohort, usually the C/D borderline, which is why then we have problems with the number of students getting a B grade or above. We have marked success in our schools by saying to schools that a C is good enough. Well, if a child gets a C but came to you in year 7 and they were destined to get an E, yes, indeed, a C is a success, because you've moved that child on; but, if that child came to you destined to get an A* and gets a C, then we haven't done a good job by that particular child. So, we need a performance measure that is much more sophisticated, looks at each individual child, tracks that progress, and measures the value added by that school in performance.
Last question: therefore, should we have confidence in the data up to 2016? Is there a lack of confidence in that data?
