The public school my son went to is rated 9/10 on greatschools and had enough kids apply to fill 7 kindergarten classes last fall. They only have enough space for 3 kindergarten classes. It is extremely popular. But the overlying attitude is that "all kids are gifted". Given that they ID up to half the kids there as GT, they aren't too far off the mark given their definition of GT. But the vast majority of those kids are at or very close to grade level achievement wise. It was quite miserable for my own HG-PG kid.
I would ask very hard and targeted questions about your particular situation before making any decisions. If we were going to return to school, we'd definitely be visiting some lower scoring schools that seem to look at kids more individually.
