Hundreds of parents and children have staged a protest against plans to expand Kings Heath Primary School.
Families fear that extra classrooms could be built on the site of the school, creating an extra 210 places for children. The school currently caters for 624 pupils.
The city council announced in March plans to extend 33 Birmingham schools in a multi-million pound drive to solve a looming pupil places crisis.
Despite assurances from city education chief Les Lawrence, who has insisted Kings Heath Primary was “very much at the end of the list” for expansion and was not being “seriously” considered, parents said they would continue to hold protests until they get written confirmation the proposals have been scrapped.
They have launched a website and gathered 1,266 names on a petition against any enlargement of the site, which they fear could involve the construction of a two-storey block of eight classrooms in the playground.
The children and parents waved placards, blew whistles, horns and sang songs warning the council to keep their hands off their beloved school.
Clare Bell, a mother-of-three and organiser of the campaign, said: “We want written confirmation this is not going to take place.
“We are not confident in the change of tone yet. There isn’t enough space and there are a lot more school where there is enough space.
“The head has been supportive and it’s important that parents express their feelings.”
Mother-of-two Saori Shibata, aged 36, said: “We will lose a significant amount of space. The plans are really ridiculous. I know there is an increase in demand for places but the council should come up with a more creative solution.”
Mother-of-two Sarah Walker, aged 40,who also works at the school on Tuesdays, said: “It’s absolutely crazy because there are schools which are empty and have been downsized in the area but they want to make Kings Heath Primary bigger because it’s more popular.
“It’s more sensible to improve the schools which aren’t popular. I have seen the overcrowding, we can’t cope with any more.”
In a statement Coun Lawrence said: “We have a duty to ensure all pupils have a school place and we need to create additional primary school places.
“However, Kings Heath Primary is at the end of the list for expansion and is not one we are considering seriously at this point.”
