My daughter is thirteen and an extremely competitive dancer. She is heading to nationals next week where she is expected to master contemporary, lyrical, jazz, ballet and tap. Most girls are also proficient in hip-hop. The main point is whether they can pick up choreography. If they can't they are toast.
That being said, many times she has been rejected and turned down for things. The last thing I would ever say would be to go home and work on it harder. Quinn's mother makes all the mothers of dancers look like "dance moms" . I'm happy that she is doing something she loves.
