Bridget and Jocelyn Bentum have collected awards from Southend United's Community & Education Trust for their volunteer work at the Roots Hall Study Centre.
The young sisters were given the club's Jack Petchey Achievement Award after glowing praise from teachers and pupils at the Study Centre.
The award recognised their dedication and commitment to the club's Community work.
As well as a certificate and pin badge, Bridget and Jocelyn were given £200 to spend on equipment for the Centre, which paid for new webcams and headphones for children to use.
The girls joined the Shrimpers' in September as part of the Skills and Volunteering section of their Duke of Edinburgh Award.
Study Support Manager Dan Ager said: "They have been a great asset to both the staff and the pupils, and are always ready to help with the activities in hand.
"They have been willing to undertake the wide range of tasks set by the teachers, and the pupils have responded well to their enthusiasm."
Community Manager and Duke of Edinburgh Award co-ordinator Stuart Fowler said: "This is a fantastic achievement for both Bridget and Jocelyn. Their enthusiasm and commitment towards the Duke of Edinburgh Award has been exemplary."
