Minister, with so many teaching staff self-isolating, it has become a real struggle to maintain even the status quo in schools, let alone providing the enhanced provision for those who fell behind during the pandemic. With PISA results as low as they are—the lowest in the UK, and on a par with ex-Soviet bloc countries—it has become very apparent that our children can't miss out on any more education. So, a ready supply of teachers and teaching assistants is absolutely necessary to address the pressures that COVID presents. Minister, what are you doing to help schools mitigate the shortage of supply teachers in Wales, and do you think there needs to be an overhaul of the supply teacher system? How are you encouraging more people into the profession, and utilising the teaching assistants to ease pressures?
