We have a model of eligibility that is based on the country's income band, so we cover low-income countries and lower middle-income countries. We also have eligibility for grants that is factored off the country's income band and also its school outcomes. That used to be factored off the millennium development goal of universal access to primary school. Now we've lifted ambition, because the sustainable development agenda is a bigger one, and it's looking at secondary school too.
So yes, countries do contact us, but when you look at that low-income and lower middle-income band, we've got very high coverage, and the partnership has grown in recent years, so clearly, countries do think that the model is an effective one for change.
