Help. My bright little 3yr old is being held back as shes very intellegant?

I'm having a few problems with the new nursery my little 3yr goes to. Im a single mom and i've just moved to a new area as i got a promotion. Shes a very good little girl, perfect really. Shes used of alot of attention as shes stunningly good looking and has been lucky enough to do a few child modelling ignments. Shes also really bright and intellegant and is way ahead of other 3yr olds in her new school with reading and understanding. Which i'm very proud of as I insisted on very little t.v or computers unless the activity as developmental qualitys. I had her when i was 20 but i made sure i still got ahead with my education and securing a really good career. I would tell her shes a beautiful child inside and out and shes turned out very confident. It was important for me to instill this in her. She is used of attending a nursery in a very upmarket area and has lots of little friends who do ballet and singing and other little princess activities. However in the new area parents dont encourage their children in these activities and i feel my little girl is being held back. Shes also started fighting with her new friends which shes never done before. I'm getting complaints about her behaviour but i feel its these children that are the bad influence as to be perfectly frank, i feel they dont have much guildance from the type of parents i've seen. To move her from this nursery to a more creative one will be much more trouble but do you think i should?
