Kevin Courtney said: “We are pleased the Government is beginning to recognise the scale of the challenge in teacher recruitment and retention and says it is willing to work with us to tackle these related problems.

“We will fully engage, and urge our members to take up the issue of workload in schools.

“But the Government needs more than ambition if these efforts are to work. School accountability needs fundamental reform, not tinkering. School leaders need to know what the Government and Ofsted expects of them, not just what they don’t expect. The Government needs to recognise that funding cuts are also now driving up workload - with class sizes increasing in two-thirds of secondary schools and teachers facing cut backs in preparation time. And the Government needs to recognise that it must deal with the growing uncompetitiveness of teacher pay.”
