The right school can make "a significant difference" in turning the education of poor youngsters, the head of a cross-party committee of MPs has said.
Education select committee chairman Graham Stuart said:
We don't know how much of the under-performance is due to poor attitudes to school, a lack of work ethic or weak parenting.
What is certain is that great schools make a significant difference in turning poor children's education around.
The problem of poor, white British under-attainment is real and the gap between those children and their better-off class mates starts in their earliest school years and then widens as they get older.
However, we also know that the effect of attending an outstanding school is transformational for poor children because it doubles their chance of success at GCSE.
