If the school is an academy, there won't be any help from the local authority. The first thing your DD needs to do is look at her contract and find out how much redundancy pay she will receive. I can't remember exactly what the statutory minimum is. I think (but could be wrong) that it's a week and half's pay for every year she's worked. However, it will depend whether she's been employed on a permanent contract or a series of temporary contracts, which is often the case with non-teaching roles in schools.
The school should have somebody in charge of HR, who should go through the options. However, in my experience, academies don't really know what they're doing with regard to employment matters. Some of them employ external companies to manage HR. Your DD should find out exactly what the situation is and then make an urgent appointment with the CAB.
Is she in a union?
