The event was sponsored by MKM Building Supplies from Dumfries, and was very well attended.
Hospitality staff handled the food preparation while students took donations and ran the raffle, which included prizes such as a beauty hamper and restaurant vouchers.
Principal Joanna Campbell said: “Our college community has a long and well-deserved reputation for generosity and helping those in need, and this latest event shows why that is the case.
“£900 is a tremendous amount of money to raise in one event and everyone involved, staff, students, and our partners at MKM Building Supplies, should be rightly proud of themselves."
