The Tasmanian Liberal Party says it will deliver on the Gonski reforms and reinvest in education if it wins next month's election.
The Liberals signed the Gonski pledge on Saturday and education spokesman Michael Ferguson says the party will deliver "Gonski-plus" if it wins the election.
"The Liberals' commitment to education doesn't stop with Gonski," Mr Ferguson said.
"A majority (Will) Hodgman Liberal Government will deliver Gonski-plus."
Mr Ferguson said under Liberal plan high schools would be extended to Year 12 and there would be 25 specialist literacy and numeracy teachers.
"We need to do more than just sign up to Gonski, we need a long-term plan that will make sure our education outcomes are at least at the national average," he said.
"That's what the Liberals plan will deliver."
And high school-aged children will have more to think about than just their studies, if a plan by the Greens to lower the voting age to 16 years becomes law.
Greens leader Nick McKim said the party would move to amend the electoral act to change the voting age from 18 years to 16 years.
"If you're old enough to get behind the wheel of a car, you're old enough to vote," he said.
"Young people today are more switched on than any generation before them. Many rightly believe they should have a say at the ballot box in choosing political representatives who will shape their future."
Meanwhile, Labor has attacked a plan by the Liberals to open extra hospital beds and deliver 15,000 elective surgery procedures, with Health Minister Michelle O'Byrne saying they will not be able to deliver on the promise.
"It sounds too good to be true because it is - they will run out of money before they have even delivered point one," she said.
