I am aware that it is the policy of NAHT to have a national funding formula. At this stage, I don't believe that that's appropriate. We have a diverse education system in Wales, whether that is delivering education in a very small rural school where the costs, obviously, are higher, or delivering education to a highly deprived community, where we know we need to put additional resources in to support those children. We have, as a Government, tried our very best in the recent budget funding rounds to protect local government spend, because that's where most schools get their resources from, through the revenue support grant. On top of that, I as the education Minister have increased the amount of money going into the pupil development grant, despite the difficult circumstances we find ourselves in. We have also identified money to assist with the reduction of class sizes in those areas where we know it'll make the biggest difference. All local authorities have seen the benefit of that investment.
