Welcome! A great place to start is Hoagies. It's an amazing web resource, with a 101 page designed just for people in your state. There's tons of info there about what gifted is (and isn't), all about testing and how to decide whether to do it, and all the fun bonus features so many of our kids come with, as alluded to above.
