My Lords, we trust school leaders to make workforce arrangements. Some schools, particularly multi-academy trusts, choose to employ supply teachers and some local authorities still run a pool supply service. As I have outlined, the agency supply deal means that there is transparency of fees and the arrangements are clear to schools, particularly when a teacher goes from a 12-week period of being temporary to being entitled to be permanent. So there is transparency—113 agencies have signed up to this deal, which we have made available to schools to help them to buy well and ensure the necessary transparency.
