The national Mentor UK CHAMP Awards is run by drug and alcohol misuse prevention charity Mentor UK and supported by drinks giant Diageo.
Three £20,000 prizes are up for grabs to eligible schemes which include after school clubs and youth community programmes.
Upward Curve is launching a media campaign to encourage eligible schemes to enter the awards. The agency will promote the shortlisted entries as well as promoting the award winners.
A shortlist will be drawn up by May, and the winners presented in November. The final selection of winners will be made by panels of young people under 14.
