What is important in academies—and, indeed, in all schools—is that we give the head teachers the maximum autonomy and flexibility to recruit the best possible people. As the hon. Lady knows, the issue we face is that although maths is the highest earning subject at degree level and A-level, it is very hard to recruit teachers. We are looking at every possible avenue to increase the level of people coming into studying and teaching maths. That will increase the pipeline, which in turn will make sure academy head teachers have the best possible pool of teachers to draw on.
