Unveiling the review, education secretary Damian Hinds (pictured below) said on Friday that some youngsters - especially those from challenging backgrounds - face "inconsistencies" in their experience of education.
It is understood ministers want to examine how exclusions are used and whether some pupils are more likely to be excluded than others.
Transforming Lives for Good (TLG), a Christian charity which trains church members to offer regular one-hour mentoring sessions to youngsters in difficult circumstances, told Premier that "injustice" plagues the education system.
Chief executive, Tim Morfin said: "The reality that kids who are growing up in poverty are four times more likely to be excluded from school just tells us that there is a real risk of a system that isn't fair."
TLG asserts that children affected by bereavement, family breakdown or poverty need additional support some schools are unable to provide due to a shortage of resources.
Mr Morfin said: "We've got some fantastic teachers in our schools who are working so hard to serve these children but the reality is that the current system doesn't enable those vulnerable children to always get the education that they need."
Government figures reveal that 339,000 state school pupils were excluded in England in 2015/16 - twelve per cent more than the previous year.
Education Secretary Damian Hinds said: "Children only get one chance at their education and they deserve the best. But for too many children - and often those who are most vulnerable - there are inconsistencies when it comes to their experiences of school and too many parents are left worried and concerned.
"That's not good enough which is why we are going to improve our understanding of these important issues and tackle them head-on."
