TSL 2018 Schools Sustainability Challenge

The TSL Schools Sustainability Challenge is a video contest for schools around the world, organised in parallel with the TSL International Schools Essay Competition & Debate.

Participating schools are invited to create a short (3 minute) video showcasing their best sustainability-related projects.

The Schools Sustainability Challenge recognises and rewards the sustainability action and leadership of schools around the world, and the winning school is awarded the Schools Sustainability Challenge Trophy, together with a cash prize of £500 or equivalent.

School-tourAs with our essay competition, schools participate in the Schools Sustainability Challenge through Teacher Champions. The Challenge is judged independently of the essay competition and debates.

Video judging takes place at the end of May, about one month before the Schools Debates.

Judging Criteria

The Schools Sustainability Challenge is judged on the quality of the projects featured in the videos and their potential replicability around the world. Views of the videos on Youtube before mid-May 2018 are also taken into account during the judging process.  Viewers are invited to show their support by viewing and ‘liking’ their favourite video entries on Youtube before mid-May 2018.
