Disability services provider IHC and teacher unions have dismissed the Government's main options for change to the $450 million education system for children with special needs.
Submissions on a discussion document on the future of special education in schools and early childhood services closed last week.
The document suggested four options: retaining the status quo, closing special schools, using them only as a resource for mainstream schools, or giving parents easier access to special schools.
The unions for primary and secondary school teachers say they want to retain the current system.
But the IHC says it wants an entirely new policy based on inclusion of students with special needs.
A decision on the future of special education is expected later in the year.
