The school was among nine high school teams to take part in the 2019 Game Changer Challenge in Dubbo on August 8 and 9.

The teams were asked to answer the 2019 Challenge question, 'How might we utilise technology for the betterment of humanity?'

Trangie Central School's solution to regional isolation was the development of an app known as Community Connect, which would profile people according to their interests and link them up with like-minded people living nearby.

While their idea didn't win, the judges highlighted the Trangie Central School solution saying it was an innovative way to deal with a real problem in regional and remote communities.

Judging panel spokesperson NSW Department of Education director Linda Doherty said the range of issues addressed by all schools had impressed the judges.

"We really felt they had addressed issues that were of concern within their own communities and had designed very practical solutions that could be easily implemented," Ms Doherty said.

The challenge was held as part of Education Week, now in its 65th year, which is an annual event to celebrate NSW public education.

This year's theme is 'Every student, every voice', which Department of Education secretary Mark Scott said was more about more than just giving students a say, it's about listening.
