Compared to other states, South Australia is like a developing nation when it comes to educating people with disabilities, Dignity for Disability MP Kelly Vincent says.
The upper house MP says the Gonski report lists SA as by far the least generous funder of education for people with disabilities, with the state spending an average of $4808 per student with disabilities a year.
The Tasmanian education system allocates $41,817 per student with disabilities each year, she said in a statement.
"South Australia is like a developing-nation when compared with regions like Tasmania and the ACT," she said.
She is calling on Education Minister Grace Portolesi to explain the numbers and explain what the state government will do to improve them.
Ms Portolesi said around nine per cent of state public school students receive disability support, with South Australia supporting a more broader range of students than other states.
"This is the second highest rate in the nation. This is more than double the rate of states like WA," she said in a statement on Tuesday.
Ms Portolesi said the state government had invested heavily in supporting students with a disability, including a $4 million increase for disabled students in the non-government sector.
"We have (also) committed $54.8 million for the redevelopment of six special schools, and a further $9 million to develop six new special disability units."
