State education agency websites
Every state department of education has a website. These sites are frequently a good source of state law, regulations, and policy regarding gifted students; many have sections devoted exclusively to gifted and talented education -- although it might take a bit of searching! Don't forget that state gifted education websites are also good sources of information.
