Education assistants who face the axe under public school reforms unveiled yesterday say students and teachers will also suffer if they lose their jobs.
The State Government said yesterday up to 350 education assistants' jobs would be cut to improve efficiency.
Kevin Davey, a father of five who has been an education assistant for 15 years, said many students had to be supervised closely because they had medical or behaviour problems.
"The kids need us there," he said. "Maybe they have diabetes and you've got to watch for signs of stress or anaphylactic shock.
"You've also got kids who just need that little bit of support, maybe their reading or writing skills aren't great, and the teacher cannot spend one-on-one time with 30 kids in a classroom."
He said the children most at risk from the cuts were those who needed help most.
Education Minister Peter Collier said all children who genuinely needed an assistant would have access.
He said assistants solely for students prone to severe allergic reactions were no longer needed because online allergy training and support was in place for all staff.
Allergy & Anaphylaxis Australia president Maria Said said teachers now had a better understanding of anaphylaxis and could manage children at risk.
"Funding for an aide to watch a single child can be better spent on managing the risk of anaphylaxis for a larger number of children through education," she said.
But Mr Davey said getting rid of education assistants for children with anaphylaxis could lead to students needing intensive medical care if they did not get immediate help.
Vicki Bennie, who works at a language development centre, said education assistants were an easy target but teachers would be overwhelmed with work if hundreds of aides were removed.
United Voice secretary Carolyn Smith said schools were already under-resourced and cutting essential support staff would not help."It is appalling that the Barnett Government has decided to slash jobs in the face of record enrolments at schools," she said.
