One teacher who took part in the survey says "in special schools biting, scratching, pinching and hitting happen on a daily basis."
A survey by the Irish National Teachers' Organisation has found 58 percent of respondents have experienced physical aggression in school.
Half of those exposed to aggression sustained physical injuries, with 41 percent of those injured requiring medical attention.
One teacher who took part in the survey says "in special schools biting, scratching, pinching and hitting happen on a daily basis."
The INTO believes physical aggression in schools is "directly linked to the current shortfalls in children's mental health and therapeutic services."
