In Tasmania, children with an IQ under 55 are put on the Severe Disability Register and are able to attend one of the state's four special schools: Northern Support School St Georges-Newstead Heights; North-Western Support School Burnie-Devonport; Southern Support School; and the Timsbury School.

There is also one independent, Giant Steps School, at Deloraine.

Others who don't meet that criteria are educated in mainstream schools and receive a limited amount of support, if any, as is possible at their school.

Lobby group founder Kristen Desmond said cases like Telejah Bowen's are not unique.

Although some parents prefer their child to attend a mainstream school, Ms Desmond said many others would opt for a specialist school and they could get the education and care they required.

``Parent's just don't have that choice in Tasmania,'' she said.

``It's not necessarily one or the other, it's about giving people that option for what would work best for their child.''

Opposition education spokesman Michael Ferguson said he supported giving parents the choice as to where their child attended school.

He said the Liberal Party was considering a number of options regarding children with disabilities.

Education Minister Nick McKim said more special schools could be an option in the future, but depended on government income, demand and educational research.

``Our existing special schools in each Tasmanian region offer parents an important choice,'' Mr McKim said.

``They're understandably well-regarded as an alternative to mainstream schools.''

He said in recent years there had been a focus on improving social inclusion and equal opportunity through mainstream education.
