Hi,
I am also taking GCSE dance, there are so many different jobs in the industry. I mean yes there is just a dancer. But you could be an Arts administrator, Choreographer, Community arts worker, Dance movement psychotherapist, Personal trainer, Theatre director etc...
I would recommend just researching different companies If I were you. As you probably know there are lots of different companies for the dances we study. Eg, Stopgap dance co, James Cousins dance company, the royal ballet, Rambert.....
Researching different companies can help because if you find one you really like you might get your mind set on it and may join it when your older.
