🏕️🥾 What a fantastic Duke of Edinburgh assessed expedition!

Fourteen pupils, split into three teams, successfully completed two days of hiking and an overnight camp in the Ogmore area as part of their assessed expedition. We are delighted to report that every pupil passed!

Their teamwork, resilience, navigation skills and positive attitude throughout the expedition were outstanding.

Miss Browning and Mr Troote are incredibly proud of you!
Congratulations to all involved on this excellent achievement. 👏⭐

This September, our Year 7 pupils took part in hands-on STEM workshops with STEM Cymru!

🤖🏁 Pupils designed and built robotic arms and legs before putting their creations to the test in a class race. They also assembled and refined wind turbines, using teamwork and problem-solving skills to maximise their output voltage.

A fantastic opportunity to explore real-world STEM challenges while developing engineering, design and teamwork skills! 👏🌟
