Homes and Property | Home Page'Build staff housing at schools'Warning: Sir Mike Tomlinson claims a widening achievement gap between children in London poses a serious threat to societyDominic Hayes|Evening Standard12 April 2012Homes for teachers should be built on school grounds to halt the exodus of experienced staff from London, a leading educationalist said today.Sir Mike Tomlinson, a former chief inspector of Ofsted, said the state sector should emulate private schools, which have long offered cut-price accommodation to teachers.Many teachers have left London in order to get on the property ladder and demand for subsidised "key worker" housing outstrips supply.Sir Mike said the Government's £45billion Building Schools for the Future programme offered a one-off opportunity to incorporate staff accommodation at schools. "We've got to be willing to think outside the box," he added.The former chairman of the Learning Trust, a not-for-profit body that runs education in Hackney, also warned a widening achievement gap between children in London posed a serious danger to society - and could even trigger riots."I think we are a million miles from that," added Sir Mike, "but we have to be careful - we don't want to sleepwalk into this situation."MORE ABOUTPrivate SchoolsTeachers
