Thank you all for great suggestions.
My DD8 likes to perform. When the school decided to accept only higher grades for talent show, she got upset a bit. That's why I am looking into opportunities for her. I will look into opportunities at nursing homes and children's hospital.
Solo festivals sound very interesting, I will do some research on that that. I hope we have it in WA.
As far as teacher, our teacher is an older teacher who teaches at her home. She doesn't do any Piano Exams. She suggested my daughter to try PAFE competition next year. She is a great teacher, but at some point, it might makes sense to move to a music school where there are Piano Exams and more chances to perform etc.
As far as goals, I would like her take advantage of her music skills when she applies for college. Playing at home and once a year at recital won't add much to her application especially when piano is a very common instrument. I might be overthinking here :-)
And one more thing about additional instrument. She is very social kid. I feel playing at a youth orchestra might be exciting for her. Piano is very competitive and not many opening in the orchestra for piano. In the long term, it might be again limiting.
