That is according to a report by the Education Policy Institute which shows progress in closing the divide has come to a standstill.
Christian charity, Transforming Lives for Good (TLG) which helps churches support struggling children says while this is nothing new, it's good for the issue to be back in the spotlight.
Explaining the reasons for the gap on Premier's News Hour, one of the directors of TLG, Paul Chenery said: "They measured it by children receiving school meals, so that is linked to kids in poverty, you have children with special educational needs, you have children that are being looked after by child services, in foster families etc and children in different demographic areas will all cause this divide and make it harder for children academically."
The Government has defended its record helping disadvantaged school children in England.
School standards Minister Nick Gibb said the Department for Education spends £2.4bn per year dedicated to supporting poorer pupils, students that receive free school meals.
He says that the gap for both primary and secondary schools was narrower than in 2011.
But, Labour's shadow education secretary Angela Rayner says this report "is the latest evidence that inequality continues to rise under the Tories, with the most disadvantaged students losing out."
Paul Chenrey says the answer is not just about throwing money at the situation: "I think you can read something like this and say putting money into this can solve it, but actually why isn't it about community? It is about getting alongside kids that are struggling, who don't have positive role models. It is not just as simple as money."
"There is a solution to it and that's the local church, getting involved and setting up education centres like we do at TLG, coming alongside kids and supporting them through not just education, but some of the wider issues they face."
At the current rate, the study says it will take 500 years to close the gap. However, Paul is confident there is a solution to this if the church and Christians get involved: "It's just thinking differently. Thinking differently about the needs of the kids and families that are in the situation. There is a real solution and something that can stop it before 500 years' time. By getting church community involved and supporting the wider needs of a child and that family."
