LES Powell School's Wheels Towards Independence program recently received a community grant of $6500 from Liverpool City Council.
The school owns four buses used to provide transport for students and their parents.
Les Powell School teacher Louise Melville, said that the money would allow the buses to be used for day outings.
"A lot of our parents are at homes and don't get to out often," Mrs Melville said.
"So this is for them to get out and see the local area.
"This is the biggest contribution we have ever got."
Ms Melville said the costs involved for the program, included travel, lunch and other excursion costs.
"Usually we meet up a couple of times per term with the parents," she said.
"But we hope to have outings every fortnight or three weeks."
The buses are also used to transport students to and from school, under the supervision of the Special Transport section of the NSW Department of Education and Communities.
Wheels Towards Independence has been running since 1991 and relies on donations and fund-raising to pay for the upkeep of the buses.
