Bridgewater School will go on to represent the borough at the county finals in June after winning the Dacorum District High Five Netball League, organised by the Dacorum School Sports Network.
The Bridgewater pupils played five pool matches during the spring term and remained undefeated throughout.
Last week, they met Two Waters School in the semi-final of the competition; it was a hard fought match with excellent play from both teams, but Bridgewater won through in the end to reach the final.
In the climax of the competition, Bridgewater met St Pauls, who had been crowned champions in each of the last three years.
It was a very tough match, with play flowing from end to end, but Bridgewater consistently marked well and passed effectively to claim the hard fought victory.
