The Tasmanian Disability Education Reform Lobby on Friday released the results of its 2015 Parent Satisfaction Survey.

More than 110 families across the state's three regions participated in the questionnaire.

The survey revealed that 67 per cent of Northern families believed the support their child received in school was inadequate, compared to 52 per cent in the North-West and 71 per cent in the South.

More than five out of every 10 students surveyed received no additional funding to assist their school to provide the adjustments necessary to help them receive an education comparable to that of other students.

Tasmanian Disability Education Reform Lobby founder Kristen Desmond said students with disability still faced discrimination.

She said some were allowed to attend school for just one hour a day and others were barred from attending school camps or playing with their peers in the playground.

Ms Desmond said the case was clear for needs-based funding over the current IQ-based system.

"It is about time that students with disability were properly resourced and this government needs to deliver on its promise to improve educational support for students with disability," she said.

"Structural reform of the disability education support system is needed now."

Education Minister Jeremy Rockliff said the government recognised that reform was required and was committed to making positive change.

"One of my first actions as minister was to appoint a Ministerial Taskforce into Education for Students with Disabilities, because we have to do more," he said.

"As a government, we have also increased funding for students with disabilities to more than $70 million, with an additional $1 million in the state budget to ensure their individual needs are met.

"We are also investing more than $6 million in new infrastructure to ensure students with a disability have the best learning environment for their needs."
