Yes, indeed, David. Yesterday, the WJEC published further information as to how grades will be designated by schools and colleges. It is designed to be as flexible as possible, and to ensure that the different experiences that children will have can be adequately accounted for in that process. So, for instance, if I could give you an example: it does not designate, for instance, how many pieces of work are necessary to arrive at an assessment, recognising that each individual student will have had a very different experience.
