Boys from Year Seven at St Edward's Academy took part in the annual Staffordshire Schools Rugby County Cup Tournament at Longton RUFC.
PE Teacher Ross Salmon said: "This is always a very tough competition which is made up of the best teams in Staffordshire.
"Twenty-eight schools took part in the tournament, including schools from the independent and private sector, and these were divided into seven pools of four teams.
"St Edward's started well winning all three of their pool matches. "The boys scored nine unanswered tries and went on to top the group.
"The second part of the tournament was organised into separate cup, plate, bowl and shield competitions.
"St Edward's got through to the cup competition which meant they played five more games against the teams who were top of their pools.
"Another superb set of displays resulted in St. Edward's winning their first four cup matches, including victory over the defending champions of the past three years, Newcastle Under-Lyme School.
"It all came down to the last game against St Joseph's College, Stoke. Victory for either team would mean they would win the tournament.
"The St Edward's boys produced a wonderful team performance, saving their best form for the final match.
"They won the game two tries to nil and were crowned as Staffordshire Cup Champions for the first time in the history of the school.
"They scored 21 tries and did not have one try scored against them.
"The boys were magnificent. Not only did they play some high quality rugby, they also displayed great sportsmanship towards their opponents.
"They were an absolute credit to the school.
"A special mention must go to the Leek Rugby Club and their coaches who came along on the day to support and work with the boys."
