The mother of a girl who allegedly was abused by an older student at an Adelaide southern suburbs school is dissatisfied with a meeting she had with the Premier, Education Minister and the head of the Education Department.

The woman said it was 'frustrating, upsetting and difficult'.

She said she contacted the Education Minister's office because the school failed to follow mandatory reporting requirements about the assault allegation.

The mother said she received no response, so contacted the Education Department's complaint unit, again getting no response.

The woman met Premier Jay Weatherill, Education Minister Jennifer Rankine and new head of the department Tony Harrison last Friday.

She expressed dismay at being forced to take her complaint to the media to get attention.

"To have that met with silence and then [Jennifer] Rankine say nothing, how can any parent be happy with that?" the woman said.

"How can any parent send their children to school and say they're going to be safe, they're going to be looked after?

"You know we have so many bullying policies and mandatory reporting - you know, the legislation is fantastic so bloody use it and, if you're not going to use it, make them accountable for not using that policy. Don't get us in a meeting and have someone come in and say 'I'm so sorry I didn't open your email' - it should never have gotten to that phase."
