Danby School saw off rivals from much bigger schools to win the tag rugby title at the North Yorkshire School Games.
The Danby team won both the Whitby area and Whitby and Ryedale stages to claim their place at the games in Escrick earlier this month.
They topped their group with victories over Clifton with Rawcliffe, Kildwick C of E, Richmond Methodists and Clifton Green and won through to the overall final, where extra time was needed to beat Monk Fryston 8-7 in a nail-biter.
Teacher and team manager Joe Houlgate said: “We had a squad of nine and every single member was outstanding. They all showed amazing attitude, teamwork and determination.”
