We're K12 as well and like that they've kept DD2 (7, SPD and more) in second grade despite her struggles with reading and speech. We've gotten over the hump in counting and suddenly she is zipping through first grade math and I expect she'll be caught up to her class mates by the end of the school year. Reading is slower going but she is identified as 2E thanks to a great school psychologist and they work with me on it. I can't give much insight on the gifted accelerations because I keep her at grade level and just to let her finish early in the easier stuff so she can spend more time doing what she wants.
Good thoughts on getting identified! We had good luck with them and got much further than our local schools
