I absolutely take that point. When I chaired the Education Committee, we did an inquiry on the importance of overseas students, who provide roughly 10% of the income of universities. That is a massive contribution. Universities are so important in our communities. The University of Huddersfield makes a remarkable contribution and is the largest employer in my constituency, and those of us who have universities in our towns and cities know just how lucky we are. Thank goodness we have universities; long may they thrive and survive. The right hon. Member for Haltemprice and Howden (Mr Davis), a former Secretary of State for Exiting the European Union, mentioned the importance of research, and that point was absolutely right.
Let me return to the broader education system. We usually judge the success of our education through evidence-based policy. How do we drive it? How do we assess it? Is it evidence-based policy? Is it going in the right direction? Are we using public money in the right way? On the other hand, we obsessively look at other countries all the time to see if we are as good as them.
The programme for international student assessment, and all that, is very important. There are deficiencies in the PISA methodology, but the fact is that those are the methods we use.
Generally, yes, our education system is improving, but a substantial proportion of children in this country are not getting the education or the opportunities. They are in particular constituencies, and we know which ones; we have all the bruises, cuts and everything else. [ Interruption. ] I am coming to the end of my speech. We know where those underperforming areas are and we have the methods—with passion and leadership—to sort them out. Our country is divided, and the Children’s Commissioner said only three months ago that 20% of children leave school with no qualifications at all. If that is the divide in our country, we have to understand that underperformance on a cross-party basis. We know the way to tackle it—and together, let’s do it.
