Students from across the community of schools were presented with awards in different categories including for contribution to the community, being a good ambassador and going above and beyond.
Bella said: “I feel truly honoured to win this award. To be recognised means so much. There are so many amazing students at our school so to win is a really a great feeling.
“I have put a lot of hard work into my studies and being a good ambassador and role model in school so it is nice to feel that you have been recognised for that.”
Headteacher Mrs Andrew-Power said: “We are extremely proud of all of the students who have been nominated and won awards this evening.
“Bella is an exceptional student and role model at Brune Park and is always the first to put her name forward to be an ambassador for the school.
“Being a part of a community of schools above all is about being able to come together and celebrate the success of all of our students.
GFM Chief Executive Ian Potter said: “The most pleasing aspect of this evening was that so many of those presenting awards were former students at GFM schools.
“They had walked along the same path, the same corridors, learnt in the same classrooms as the young people they were helping to celebrate.
“That is an incredible powerful message to give to the young people of this town; that if you work hard and have the right attitude there are no limits to what you can achieve.”
