The Sutton Trust educational charity has published a study which examines how social mobility has altered in the UK in recent decades. The research was carried out by the LSE, and has suggested that social mobility has been largely static in Britain since 1970. This means that clever children from poor backgrounds can often be overtaken in their education by less intelligent children from affluent families.
The report is entitled Recent Changes in Intergenerational Mobility in Britain, and can be read in full online now. A summary version is also available to read.
