GREENHEAD College has won the Kirklees heat of the Young Consumer of the Year contest.
It was hosted by West Yorkshire Trading Standards.

All the members of the teams received goody bags of prizes.

There, they will meet other teams from around the county.
Martin Wood, West Yorkshire Trading Standards chief officer, said: "The schools showed they had studied very hard.
"My congratulations go to Greenhead and I wish them luck in the regional final."
