A conference this weekend, titled London Schools And The Black Child, will assess today's report and bring together education chiefs from across the city. In a foreword to the report, Mr Livingstone said the failure of schools to improve results for black boys over the years had been "catastrophic". He pointed out that last year only 2.9 per cent of London teachers were Afro-Caribbean, while the proportion of black pupils, at 19.6 per cent, was more than six times higher.
