Enviroschools learn to integrate environmental sustainability into school and community engagement, and reflection stages remind pupils what they have achieved.
Activities have ranged from building a compost system and growing their own food to better waste management, roadside cleanups, hosting community events and navigating bureaucracy to raise funds.
"Council [Clutha District Council] came around the schools to say they had money to spend and ask the children what they might like to use that money for," principal Sue Adcock said.
"After discussion they decided to upgrade our old basketball hoop and some of the boys set about the formal proposal and paperwork to access that resource."
The boys researched and set their sights on a modern, adjustable goal, pitched the costs and plan to the council and got the green light.
"Unfortunately we forgot the freight cost and were $300 short," spokesman Flynn Jenkinson said.
"So we organised a fundraiser around shooting basketball goals and ended up raising about $1500."
The surplus was invested in other school projects, and after the state-of-the-art hoop was installed, the team went to the council chambers to deliver a thank-you speech.
"Engaging with authorities for things like planning and consents and accessing funds is vital for community and environmental projects, and our students now have some firsthand experience of that process," Mrs Adcock said.
At the bronze-stage reflection, pupils recounted their work, accepted certifications and thanked members of the community who had helped.
