The school, which is part of the Grantham Additional Needs Fellowship, caters for pupils between the ages of 3 and 16 with moderate to severe learning difficulties and complex needs.
It organises regular volunteering programmes for pupils to strengthen their social skills and help them to make a difference in their local community.
Alex (15), Malcom (14) and Ruby (14) have been visiting Grantham's award winning parks to take part in a litter pick.
Alongside Council-employed Park Keepers, they have been helping to keep the area clean and tidy for visitors.
Dawn Prentice, a Teaching Assistant from the Ambergate Sports College who focuses on work experience opportunities for the pupils said: "Volunteering opportunities are crucial for our pupils as it gives them a chance to see the value in making a difference in their local communities."
"It has been a great experience for all pupils involved and we're thankful to staff at SKDC who have facilitated the experience. It has made an enormous difference in helping our pupils to socialise and build their team-work skills outside of their usual environment."
Alex, Malcom and Ruby will continue visiting the park until the end of the summer term.
