The performance of Durham Free School will be debated by MPs next week.
Labour's Durham city MP Roberta Blackman-Woods will lead the debate in the House of Commons on Tuesday (27 January). A minister from the Department for Education will also take part.
This comes after Education Secretary Nicky Morgan announced plans to close the school. That decision was prompted by the school getting the lowest possible rating in an Ofsted inspection.
Durham Free School is set to opens its doors for the first time today.
It follows a two-year campaign by families who were struggling to get their children into Durham Johnston School who then went on to set up their own school.
The Durham Free School (DFS) will open in the former Durham Gilesgate Sports College in Gilesgate.
Nine teachers will care for 31 year seven pupils from Durham, Bowburn, Coxhoe, Spennymoor and elsewhere.
The school will be funded by and responsible to the Department for Education.
