Primary school children at Paxton Primary Academy on Brigstock Road are facing their fourth year of being taught in Portakabins.
The school opened in temporary accommodation in 2014, with a promise it would move into a new permanent site on London Road within a year.
Last month MP Steve Reed challenged the Schools Minister to meet with him, parents, governors and the head teacher to find a way forward for Paxton Academy.
The MP said: “The Government can no longer stand idly by while children’s education is put at risk. Our children deserve better than this.
“Three years later work has still not started on the new building. Children are taking their lessons in Portakabins piled up in the back yard of a rugby club with hardly any play space.
“It’s shocking that a school can be left like this for four years. The cause of the problem is not difficult to find.
“The Government has failed to manage their free schools programme properly, leaving parents angry that the school building they were promised has never been built. “
