It was conducted in April this year, with more than 2,000 participants across different geographical areas.
That statistics show that schools are providing £43.5 million of unfunded support for children.
The report found schools are frequently providing food, clothes and washing facilities, and even birthday presents, to children from poor families.
Clive Ireson, from Association of Christian Teachers told Premier's News Hour that some schools are really struggling to cope. He wants the new government to help lift children out of poverty to give them a fair chance.
He said: "So many children are in great need in our schools, and of course it's disproportionate, some schools won't have any children like that but they'll be some schools that have hundreds of children needing this type of support.
He added: "It's not the teacher's responsibility, but quite rightly teachers step up to the mark, because if a child hasn't eaten, if they're not clothed properly then they're not going to learn - and learning is about what teachers are about.
"You can't miss out the other bits, if a child hasn't had any breakfast they need something to eat so they can concentrate."
