Just to drill down rather deeper into the issue of the variability in the way in which the Welsh bac is provided, could you explain why you think that this inconsistency is happening, and then what the impact of the inconsistency and variability is on the value that learners attach to the bac and their understanding of it?
I think the variability can be perhaps explained by the fact that it's a new type of qualification, the fact that different schools have adopted it at different rates—
Ten years?
Well, as I said, over that time, there were some early adopters who have done it in a certain way, there are some people who've come later to it, who may be doing it in a different way. And, as I said, it's quite a different departure from traditional O-levels, from GCSE-type subjects, where there is a programme of work and a syllabus. So, it is a different nature of qualification, and, therefore, as Andrew has just alluded to, schools have approached it in a different way. We are alert to that and Qualifications Wales, crucially, is alert to that, and we are looking to ensure greater consistency in how it is delivered in individual schools. We're also aware, in the school setting, in pre 16, there are some concerns about the onerousness of the workload associated with the evaluation of the students' work. Now, clearly, there is a difference between onerous and rigorous. We wrote the qualification to be a rigorous qualification for the students, but we don't want it to be jeopardised by the evaluation of it being too onerous. So, there's that balance to be struck. Again, that's one of the issues that the design group and Qualifications Wales are looking at. That process is a really important process, so there is the design group, but working alongside the design group, who they are testing the messages and testing their thoughts with, is a stakeholder group, and there is also a practitioners group. So, that work by the design group is being tested with those people who have an interest: business, for instance, the world of work—is this qualification really giving students the skills that are valued by potential employers?—but it's also testing its thinking with the practitioners, those people who will be charged with the delivery of the qualification, and I think that's really important to be able to get an understanding of the challenges of making sure there's a consistency, and what are the barriers to that, and what steps need to be taken to ensure a greater level of consistency in delivery.
