BRUNTCLIFFE High School is asking everyone to back its bid to become a national champion.
The school has made the final three of the national Social Enterprise in Schools schemes and its fate is now in the hands of the public.
Pupil Rory Huggins-Briggs, 15, visited 10 Downing Street this week to meet the Prime Minister and launch Bruntcliffe's campaign to win the title.
Among those backing Bruntcliffe's bid is former pupil and Leeds United star Jonny Howson, who helped with the campaign last year.
Earlier this year the school was named the Yorkshire and Humber Champions for their work on social enterprise activities which include growing and selling fruit and vegetables, making planters, animal homes, hanging baskets and undertaking construction work in the local area.
Around 100 young people are involved in the projects which are designed to give students and understanding of the business world, raise aspirations, boost confidence and support community projects.
VOTE FOR BRUNTCLIFFE: Go to www.socialenterpriseawards.org.uk before November 30.
Rory, who said the highlight of his visit to No 10 Downing Street was sitting in the cabinet room at the table where so many important decisions have been made, said: "The social enterprise department has changed the way I work at school.
"I enjoy school a lot more and I am more aware of the world around me.
"I really want to run my own business one day because I was inspired by the competitions we entered.
"My confidence has grown and I really enjoy talking to people and using my business skills."
He and the other pupils involved in the project now need people to vote for them to win before voting closes on Monday.
Headteacher Lynda Johnson said: "It is wonderful that we have reached the national final and are competing to be the best school in the country.
"Rory loved meeting the Prime Minister and it was day he will always remember. We now need as many votes as possible to help us win the national title – which would be a fantastic achievement for everybody involved in the project."
Chris Edwards, chief executive of Education Leeds, said: "Bruntcliffe School has done brilliantly to reach the national final of this prestigious award – and definitely gets my vote for the fantastic work it is doing in social enterprise.
"Everyone at Bruntcliffe should be proud of reaching the final and I hope they are named the best school social enterprise in the country."
Winners in each of the categories will receive 1,000 each, while the overall winner will receive a cheque for 5,000.
