Parents, teachers and governors from Acton Park Junior School are protesting at plans to amalgamate it with Acton Park Infants School on the same site.

Since a meeting held at the junior school in April to form a fighting committee, the group has moved its protest forward by writing letters to Wrexham Council's education director Hywyn Williams, letters to all councillors, started a petition and even put posters up at polling booths.

They have also prepared banners and plaquards ready for the executive board meeting at which the matter will next be discussed.

"We've had some replies but they don't answer our main question which is what will be the main advantages of the amalgamation, if any," said teacher Simon Kane.

"We're still in the unofficial consultation period and don't know when the official consultation period will start. We're expecting it to go to executive on the third Tuesday of June and are hoping to get a lot of parents there waving some banners.

"We're working on a major report for someone to issue on our behalf at the meeting.

"What we're trying to say is in some schools amalgamation is a good idea but not in others."

One of Mr Kane's main concerns is that an amalgamated school could prove too big to manage by one headteacher and points to Grazebrook Primary in Hackney, East London, the school where education secretary Ed Balls' three children attend.

The school is under threat of closure after a disastrous Ofsted inspection saw it put on special measures. "There has been comment made that it was too large to manage," said Mr Kane.

Annette Bryden, of Chester Road, works at Acton Park Junior School as a teaching assistant and is also a parent governor. Her daughter Sioned, 10, is in year nine and son Ieuan went the school and is now at Ysgol Rhosesni.

"My concern is that the amalgamation of the school is not of educational benefit to the children that are here," she said.

"It's too big a job for one headteacher – they would lose the personal touch and knowledge of the children. If I could see there would be benefits that would be different but I can see more negatives than positives.

"The LEA have given us generic answers to questions raised by parents, not specific to Acton Park. Some responses are geared to schools with surplus places or difficulties with funding but Acton Park is full.

"They're not backing their answers up, we've requested evidence of how the education of children will be improved and it's not being provided."

Hywyn Williams, Wrexham council's chief learning and achievement officer, said: "As we are in the middle of a consultation exercise it is not appropriate for us to comment."
