Isla dances with the Christine Paul School of Dance on Wednesdays and said she practised about five days a week.
She has been all over the country to dance and this was the third year she had competed in the national competition.
Isla would like to convince other youngsters to learn Highland dancing. Not many people did it and there were lots of opportunities to make friends.
Isla's nana, Dianne Sligo, said Highland dancing was in the family. Mrs Sligo danced for many years, as did her daughter, Isla's aunt.
"Isla's learned six dances now and is learning her seventh."
When asked what made Isla so good at Highland dancing, Mrs Sligo said much of it was down to practice.
"It's that old story, practice makes perfect. She's got a good brain so she can remember things and she listens to her dance teacher. She tries really hard and seems to be able to lift herself at the big performances, like you have to do."
