From BBC:

David Cameron is to announce a £15,000 university bursary for teenagers with good A-level maths and science grades, if they commit to enter teaching.

This “golden hello” for teenagers is an attempt to recruit more maths and physics teachers for England’s schools. […]

These will begin with pilot projects, with a so far unspecified number of places, which will see incentives for young people to sign up for teaching before going to university.

The £15,000 over three years for potential teachers would help with living costs and would be repayable if students did not go on to teach for three years after graduating
