TEACHERS’ leaders warn that staff taking part in the Government’s Excellence in Cities project will face an extra burden. Estelle Morris, the schools standards minister, confirmed that the 17 education authorities to be inspected next spring would include all remaining authorities involved in Excellence in Cities. Chris Keats, assistant secretary of the National Association for Schoolmasters Union of Women Teachers, said if the Government wanted schools to co-operate in a major project it should not push these authorities up the inspection list.
