The vibrant little school was among 300 across NSW to open their grounds to the public for the spring break as part of the Share Our Space program.

Glenroy's principal Sean Scott said the idea was to foster the school environment as an integral part of the community.

"We opened the school for community to use during these holidays," he said.

"It's another way to encourage children off their small screens and into physical activity in our safe, outdoor spaces and shaded play areas."

Families were invited to use the play equipment, basketball courts and even familiarise themselves with areas around the classrooms from September 30 to October 11.

A security guard was present at the grounds and areas were cleaned regularly to keep everything ship-shape.

Mr Scott said there was another equally critical component to making the school grounds accessible during this holiday period.

"It coincides with our Tiny Treasures program, which helps to transition our incoming kindergarten students for the next year," he said.

"It starts mid-way through Term 3 and includes pre-school visits and the opportunity for the new kinder students to attend school one day a week for 10 weeks.

"The children get to know the routine and structure of school and we are able to get our eyes on them and pre-plan if any thing extra needs to be put into place."

The Share Our Space program provided another opportunity for the 2020 kinder students and their families to explore and familiarise themselves with this new environment.

Glenroy Public School was one of the first to take part in the NSW Department of Education pilot program at the beginning of last summer.

Share Our Space recognises public schools as "the beating heart of the community".

"They belong to everyone and should be a place of togetherness and local pride," the department has stated.

Glenroy's principal is equally proud in acknowledging the "culture of professional learning" for staff and tailored individual learning for all students.

The school hosted a five-day MSL course for 14 teachers and support staff from nine school schools in the region during the first week of the school holidays.

Mr Scott said they were seeing "significantly less behaviour issues" through their efforts to engage students.

"There is no teacher at the front; small-group work gives students more ownership over their learning."
