By the numbers - Free school meals pupils
The government has set out plans to improve social mobility and boost the attainment of children from poorer backgrounds.
Former Labour minister Alan Milburn, who is leading a commission on social mobility and child poverty, has listed 17 measures that should be monitored to show the impact of government policies.
These include the number of two-year-olds receiving early education and how the pupil premium is spent on children who receive free school meals or are in care.
The indicators, set out in a report last month, also include school readiness at the age of 5, GCSE and A-level grades and access to the professions.
A report published by the Organisation for Economic Cooperation and Development earlier this year highlights the gulf that currently exists between pupils from richer and poorer homes.
