13 February 2017
Researchers from the Centre for Economic Performance at the London School of Economics, Surrey University and University College London, compared data on children's results with information on nurseries attended in the year before starting school for around 1.8 million youngsters born in England between September 2003 and August 2006. The findings showed that children who attended a nursery that employed a graduate have a teacher assessment score around a third of a point higher, where the total number of points available was 117.
