The Youth and Philanthropy Initiative is designed to teach 14 and 15-year-olds about effective giving.
Participants work in groups to identify a local social service charity that can best address the needs of their community.
Each group in the school then pitches their chosen charity to a panel of judges, who award a £3,000 prize to the winning charity.
The programme was set up in Toronto five years ago by entrepreneur Julie Toskan Casale, co-founder of MAC Cosmetics.
It is now being piloted at Parliament Hill School in Camden, north London. In September, the scheme is due to be expanded to 10 other London schools.
The Institute for Philanthropy hopes that 100 schools in the UK will be running the programme within three years.
