This is a fairly unique charity. It has an impressive track record in reducing dropout rates. It has been in place in Regent Park in Toronto since September 2001 and has reduced the high school dropout rate from 56% to below 10%. I'm not personally aware of other organizations that have the scope and inclusiveness of the programming provided to high school students, but there may be others. I'm not an expert in the field.
