More than a fifth of state-educated pupils receive some form of private tutoring, a poll for the Sutton Trust reveals. In London, 43 per cent of young people have been helped by a tutor during their school years, an increase from 36 per cent in 2005. Tutoring is least common in Yorkshire and Humber, where 11 per cent have tutors, according to the Ipsos Mori survey of 2,447 secondary pupils. Sir Peter Lampl, chairman of the Sutton Trust, said: “The danger is that this boom will widen the gap between the haves and have-nots.”
