DD will be in 3rd grade in the fall. I recently checked out an "alternative gifted" charter school. I think that it would be perfect for her but the waiting list is huge even though they have only been open since the fall. Their director suggested finding other 2e parents and starting my own charter like this. (LOL) I haven't really looked at anything else.
PM me if you are in the northern Colorado area, but I am thinking you are further south in that I don't know of any new gifted charters (or actually any gifted schools at all) in N.CO. I'm working on resources and options up here including seeing if I can get enough gifted/divergent kids together to make a hs co-op, afterschool program, or something like that.
