Kindergarten Assessment?

I'm being told by my childs preschool teachers that she is smart enough for kindergarten but before I call the school to find out about this I would like some information of my own. So, my question is, are the any online resources I can use to test my daughters skills? Any sort of pre-K assessment test or anything. And one more thing, she is in 3 yr old preschool since her birthday is in Nov. She will have to take 4 yr old preschool next year since she wont be 5 when kindergarten starts.
