The 38th annual show features 200 dancers from as young as 2 to 21 years.
Duder-Joy said most of the choreography for the show is done from July and extra rehearsals are held in the lead-up to it.
"The end-of-year show is the highlight of the year. It is what both teachers and dancers work all year towards. It is our opportunity to entertain family, friends and the community in a professional theatre setting."
Duder-Joy said this year had shown the resilience and determination of the dancers and she couldn't wait to see them on stage.
"My favourite part of the show is seeing the excitement and anticipation on the dancers' faces as they take to the stage, even if this isn't the first show for them."
Keep Calm and Dance On is at Forum North's Capitaine Bougainville Theatre at 6pm on December 4, and 1pm and 6pm on December 5.
