MP Steve Barclay has raised questions with Cambridgeshire County Council over the proposed merger of the two schools.
He is asking why the county council’s advisors did not raise wider concerns about Maple Grove after an inspection last February found three teachers requiring improvement.
The school was placed in special measures during the autumn.
Mr Barclay said: “Where individual members of staff have failed to perform it is right in the best interests of the education of children at the school, that this is robustly managed. However, today’s announcement treats all staff the same, both good and bad. It leaves administrative and support staff in limbo and parents with a consultation which appears to present only one option.
“It is important in the coming weeks that we maintain the morale of all involved in the school as best we can while lessons for children progress. We need to get decisions as quickly as possible to address the inevitable uncertainty that staff and parents will feel.
“I will work closely with the governors and others to ensure children get the best education they can in whatever arrangements are put in place following consultation.”
He also says that the authority accepts that there will be a cost saving to the plan.
