. "That's why I am so pleased to be launching the Workload Challenge and to work with the profession to develop solutions that will help us to reduce unnecessary workload."
The teaching unions welcomed the move, but warned that the survey's results would be uncomfortable reading for ministers. "Ultimately, teachers' workload will only be reduced when politicians learn to respect the demanding and difficult work that teachers and school leaders do," said ATL general secretary Mary Bousted. "Regrettably, we are still some way off that."
The NASUWT said that the government had not reduced teachers' workload in its four years in power, despite being given detailed evidence of excessive hours.
According to the Organisation for Economic Cooperation and Development, teachers in England work 48 hours a week on average, with one in 10 doing 65 hours or more. Most of their time is spent on administrative tasks, producing detailed lesson plans and marking. The OECD's statistics show that teachers in England work longer hours than the rest of the world but spend less time in the classroom - 20 hours a week on average.
The Workload Challenge was backed by deputy prime minister Nick Clegg. Visiting a school in South London, he said: "It is time for us to stop that runaway train of bureaucracy in its tracks."
Survey responses from teachers will be fed back to a panel of teachers and education experts in the new year. The panel will work with the profession, teaching unions and Ofsted to put forward recommendations.
Shadow education secretary Tristram Hunt also made his case for how the Labour Party would help to free up teachers' time this week, calling for a period of stability in the curriculum, "intelligent inspection" and "sensible management".

Wendy Exton, who teaches at the Aspire Academy, a special school in Bath, says she is "sceptical" about politicians' calls for action.
"We have a general election coming up so I think that is partly to do with it," she says. "I think they've realised how demoralised the profession has become due to the reforms of [former education secretary] Michael Gove and they are now trying to counteract that."
Ms Exton says workload is more of a problem now than at any time during her 20-year career. "When I started it wasn't this bad," she adds. "The last three years have really tipped people over the edge.
"The problem is Ofsted. There needs to be evidence for everything; you can no longer use your professional judgement. Tackle the problem with Ofsted, then you can address the problem with teacher workload."
