Galston High School was recognised as the champion school at the 2013 Castle Hill Show.
The school was recognised for their efforts in a variety of exhibits including apiculture, poultry, arts, crafts, cooking, horticulture, equestrian and visual arts and photography and teachers were awarded the Agriculture Teachers Association Prize for overall point score winners in all categories.
It was the 22 second year the school won the award, of a possible 23 years.
A school spokeswoman said the school continues to be involved in the show because it allows students the opportunity to display what they have learnt across a wide variety of school subjects.
She said the school is proud of its strong links with the local community and is thrilled to be able to participate in community events such as this.
