The ACT Education Directorate can expect to lose the equivalent of 100 staff although Education Minister Joy Burch insisted there would be no forced redundancies and teaching jobs would not be lost.

The directorate's workforce will need to shrink from 4765 to 4666 or make efficiencies in the order of $6.2 million - the largest saving requirement of any ACT directorate outlined in Tuesday's budget.

Ms Burch said she expected the job losses to come through natural attrition with annual staff turnover levels in the directorate between 300 and 400 each year.

Catholic and Independent schools can expect to receive more than $19 million in additional funding over the next year due largely to the ACT signing up to the Commonwealth's Gonski reforms.

This will take total non-government spending to just over $60 million.

While the ACT and NSW remain the only two jurisdictions to have signed up to the package, Treasurer Andrew Barr said he did not believe an incoming Coalition government would claw back any of the funding promised under the deal.

According to internal ACT costings, the $190 million six-year package will result in local Catholic schools receiving the lion's share of new money flowing to the non-government sector.

By 2019, the ACT's 28 Catholic schools will receive an extra $198 million compared with $100 million in new funding for 17 independent schools.

The ACT's 86 government schools will receive $347 million in new money.

The $900 million education budget contained $80 million of new capital funding including $10 million over three years for computer maintenance and upgrades in government schools and $2.5 million for non-government school information and communication technology.

A new Coombs Primary School and Preschool will be built in Molonglo with $550,000 to complete its design this year with plans to open in January 2016.

Belconnen High School will receive a $2 million refurbishment while non-government schools will share in $5 million to establish or upgrade their preschools and government schools will share in $3.5 million for ongoing repairs.

In an attempt to ease the financial stress on school canteens, the government has earmarked $200,000 for the ACT Council of Parents and Citizens Associations to run canteens in government schools and introduce an online ordering system. A further $500,000 will provide water refill stations across selected government schools in an attempt to phase out sugar-filled drinks.

The Canberra Institute of Technology will consider how to provide the best vocational education for students in Woden Valley, Weston Creek, Tuggeranong and Molonglo through a $180,000 feasibility study.

Students with disabilities will receive $1.6 million for transport to and from government schools while $1.3 million will fund additional support in the classroom.

The Wanniassa Hills Primary School will receive $1.8 million over two years to establish an introductory English Centre to help students with a limited background in speaking English.

The Secondary Bursary Scheme will also be increased by $550,000 over four years to provide selected low-income students with $750 a year - up from $500.

Childcare centres and childcare workers received added support through a $2 million upgrade of government childcare centres and $240,000 for childcare workers to complete their qualifications under new Commonwealth requirements.

Non-government preschools will receive $5 million over four years to upgrade facilities or build new ones.
