Could You help me find my skill level for piano?

Hi, if anyone could give me an idea of what piano skill level im at it would be great. Im 16 years old and have been playing since i was 6 (mainly clical) , I can sight read pieces pretty well, and just joined the jazz band at my school, and those pieces im just ok at, but i cant read the notation very well, and right now im learning the piece rondo alla turca, but i also learn a lot of other pieces on the side such as: Solfeggettio, Prelude in D minor, and a few others. Please if i need to step it up a notch please tell me cause i want to be the best piano player I can be, and sometimes i worry that im not good enough (low self-esteem)
