Schools in England have been warned that if they coast, rather than improve, they risk being closed down. Sarah Montague meets the new head teachers of a Birmingham secondary school involved in the so-called Trojan Horse scandal. Golden Hillock School re-opened in September with new leadership, and became Ark Boulton Academy , where some of the students have seen four different head teachers in four years. Now, principals David Gould and Herminder Channa plan to take the school out of special measures and introduce higher expectations for students, staff and parents. Their promise to students is that they will learn everything they need to go on to university or a career of their choice, but it will require focus, discipline and hard work from students, staff and parents.
