As about 500,000 families in England are allocated secondary school places, research shows that the richest children dominate top state schools. Analysis of official data shows 43% of pupils at outstanding secondaries are from the wealthiest 20% of families. The study from education charity Teach First also shows poorer pupils are half as likely as the richest to be heading to an outstanding secondary school. Ministers said plans for new grammars would create more good school places. Under the admissions code, state schools in England must follow strict rules to ensure fair access to school places.
