Thank you for that question, Darren. Securing, nurturing, and inspiring school leaders now and for the future is an important priority for the national mission. That's why, last year, we launched the National Academy for Educational Leadership Wales, so that we can better support those who are already in the job, or those who aspire to leadership in our education system, to get the support that they need. There are statutory measures in place to support all employees, including teaching staff, to maintain their health and well-being. And, as you will be aware, we are undertaking work with how we can ensure that schools are places where well-being can be nurtured, and that's as important for the staff as it is for the pupils within the school. We will be working—. As you will be aware, a number of reports have been commissioned and workstreams are under way with regard to workload. One positive example has been the introduction of the business manager pilots, which takes tasks and duties away from headteachers so that they have got more time to think about curriculum and teaching and learning. And we will continue to work with our local authorities, the regional consortia and the headteacher unions themselves to see what more we can do. Of course, we demand high standards of our school leaders; they are integral to the delivery of the national mission, but obviously we want to do that in a way, as I said, that is nurturing and supportive, not punitive, and, of course, our reforms to curriculum assessment measures have an important part to play in that.
