THE state government has been accused of being "glib" after saying it understands the frustration felt by parents of children with autism who are still waiting for news of a specialist secondary school promised for Melbourne's west.

Western Autistic School at Laverton and Niddrie caters only for children in prep to grade 3.

Western suburbs' parents, some of whom have been forced to move home because their children have to leave school at the end of grade 3, this week rallied to put pressure on the government.

James Martin, a spokesman for Education Minister Martin Dixon, said the government understood parents' frustration.

"We understand the west has previously been overlooked when it comes to the provision of services for children with disabilities and children with autism.

"The government is committed to rectifying this situation and ... is working with parents and the school community to achieve a positive outcome as a matter of priority."

Danny Sorbello, whose son Dante will be forced to leave school at the end of the year, said parents wanted definitive answers.

"It's more than disappointing that the government is taking so long to release its review into autism education in the west. It's not helped by the glib response from the minister's office that displays a lack of awareness of parents' stress."

"Parents need to make decisions about their kids' schooling and for many parents that means moving house to get closer to a suitable school for their kids and this delay is adding to that stress."

On Monday, Mr Sorbello met Western Metropolitan Greens MLC Colleen Hartland, who urged the government to listen to parents and not leave families in limbo.
