Yes-- but know that in some states, the mandate for identification really doesn't apply to kids in K-2. My state is one of those.
We were looking at a kindergarten setting where kids in the "top reading group!" were anywhere from Bob books to start and Henry and Mudge by the end of the year... to... kids like mine who were already devouring Harry Potter books at a nearly adult rate. They didn't see any difference between those two students, or provide anything different for them instructionally. Until. third. grade. At that point, there are "enrichment" programs and once a week pullouts. (Woohoo.)
(To be clear, this is obviously crazy.)
If that is true, then really, you're more or less stuck with afterschooling or acceleration (provided that you can advocate for it).
I guess what I'd add to Evemomma's advice is to investigate what your state does for GT kids and how it identifies them and when. That way you KNOW what your options are-- and whether or not you're asking for the moon right away, or something more routine, if unusual.
