Eluned Parrott is calling for urgent action to address the shortage of secondary school places in the North of Cardiff.
Demand for places at Cardiff High School, St Teilo’s CIW High School and Llanishen High School far outweighs supply, and many children who live in the school catchment areas are losing out.
At Cardiff High School, 635 children were put forward for the 240 places available leaving hundreds of children without a place.
Lib Dem campaigner Eluned Parrott said: “It really is unfair for so many children to be losing out on an education at the school of their choice.
“I’ve been contacted by parents living in Cyncoed, Penylan and Pentwyn, who all live within the catchment areas of their preferred school, but who are being denied a place for their children.
“The situation is likely to get worse due to Cardiff’s rising population and many families face an uncertain future on where their children will be educated.”
For many years the Labour Welsh Government pressurised local councils such as Cardiff to close school places. Now there is a shortage across the city.
Eluned’s call for action has been backed by Lib Dem Councillor Joe Carter.
He said: “A lot of parents are distressed that the situation has come to this. Cardiff’s population didn’t just increase overnight so I can understand their anger that something hasn’t been done before now to address the problem.”
Eluned is calling for an urgent review of the situation to ensure that more children can attend the local school of their choice.
