Active students at Cox Green School in Maidenhead showed off their moves on Thursday as they were crowned this year's Rock Challenge UK regional champions.
The school sent 100 students aged between 11 and 18 to the southern open final of the dancing competition in Portsmouth Guildhall and beat 12 teams to come out on top.
The winning dance consisted of an eight minute routine based on 1920s silent movies with pupils dressed in vintage costumes donated by parents.
Head of drama at the school in Highfield Lane, Laura Abbott, said: "The students are over the moon.
"I'm very proud of them."
The achievement means the school will join the elite premier league of the competition next year which will involve the top 12 schools in the southern region.
The team also won awards for best choreography, crew, set design and performance skill.
The Rock Challenge is run by the Be Your Best Foundation, which encourages young people to avoid tobacco, alcohol and other drugs.
