A series of public meetings to discuss a major shake-up of secondary and sixth form education in Powys start in Welshpool later.
They will be held at the county’s 13 high schools and three further education colleges over four weeks.
They were due to start last month, but when head teachers collectively raised concerns about the expected high turnout they were re-arranged.
Under plans by Powys Council, schools could merge and sixth forms could shut.
The local authority approved plans to radically transform secondary education last December, and it could mean that seven or eight schools could operate across 13 sites.
But the proposals are strongly opposed by union leaders who fear heavy job losses.
The proposals for post-16 schooling include stripping schools of their sixth forms and opening sixth form centres or working in partnership with the county’s further education college, Coleg Powys.
The council has said its options are a response to falling pupil numbers and the condition of buildings.
Councillor David Jones, who is responsible for schools, said: “The authority, schools and the college are facing serious challenges.”
But Newtown councillor Russell George, one of three board members to vote against the plans, has said he does not believe there is an economic case to justify the change.
“It is imperative we do nothing that harms the present provision,” he said.
