Teachers would receive a $200 voucher to buy school supplies at the start of each year if the Canberra Liberals are elected in October's ACT election.
The opposition has also promised to add $25 million to an asset renewal program to upgrade heating, cooling and toilets in public schools.
There would also be an audit of ACT government schools against new standards which the Liberals have promised to finalise if elected.
The Liberals have also committed to fully implementing system-wide initiatives recommended by an expert panel which reviewed literacy and numeracy education in the ACT.
This plan includes evidence-based teaching practices, year 1 phonics, small group intervention and supports for students and regular monitoring of progress across all years.
The government is implementing similar changes but only $1.7 million in new money has been allocated to the program. There will be $24.9 million spent over four years but this is coming from redirected resources within the Education Directorate.
But the Liberals say a full implementation of the plan will cost nearly $100 million. This is similar to an estimate from the ACT Alliance for Evidence-Based Education and Equity Economics which said it would cost more than $92 million over four years.
The Liberals would also introduce an opt-in behaviour curriculum for students. Schools in the Canberra Goulburn Catholic Archdiocese are trialling such a program, which includes implementing consistent rules and routines.
'Let down an entire generation of students'
Opposition Leader Elizabeth Lee, who is the opposition's education spokeswoman, said she wanted the ACT to have the best education system in the country.
"The Canberra Liberals have listened to the advice of teachers, parents and education experts, and will deliver a clear plan to improve literacy and numeracy, better support our hardworking teachers and ensure all students have access to well maintained and safe learning environments," she said.
"The Education Minister [Yvette Berry] and her Labor-Greens government have let down an entire generation of students by ignoring report after report from experts which raised the alarm that what this government was doing was not working when it comes to teaching literacy and numeracy."
Ms Lee said the vouchers would help teachers who were often forced to buy supplies for their students.
"We have heard from many teachers that a lot of time they are putting their hand into their own pocket to purchase school supplies," she said.
"Teachers know best what they need in their classroom and we'll make sure that we give them the $200 voucher so they can buy some of the items that they want to create for their classroom."
Labor government sceptical
Chief Minister Andrew Barr said he did not think the Liberals' announcement for vouchers would achieve the necessary outcomes.
"I think there are better ways to achieve the sort of outcome that I think we all want for resources within our public system," he said.
Instead, Mr Barr pointed to ongoing negotiations with the Commonwealth on increasing federal funding for public schools.
The federal government has promised to increase funding from 20 per cent to 22.5 per cent but the ACT and other states want the Commonwealth's contribution to increase to 25 per cent.
Mr Barr also did not believe the $25 million extra to renew schools would add much more to the program.
"We have already budgeted hundreds of millions of dollars, more than $600 million, for work across our public education system so an announcement today from the Liberals of only an extra $25 million. I don't think it will achieve what they are stating," he said.
Ms Lee said the extra $25 million was only a starting point for funding.
"This $25 million boost is the start and the start is to ensure that we have funding available to improve the heating, the cooling and adequate toilet facilities as a priority," she said.
"This is a bare minimum and what we are announcing is a commitment of $25 million as a start, as a down payment if you will, to ensure that those basics are brought up to scratch."
