I live in a good state but, a low achieving county.

I would say that it is easier grade skip, even multiple times, in the lower achieving schools. The flip is that smart kids are more likely to get picked on in this environment. I will also note that the district gifted program around here is a joke, because the main focus is to bring the low achievers up. They are the reason we are not meeting State Standards.

Around here the highest performing schools are not as open to grade skipping. They have a higher number of smart students so the gifties don't stand out quite as much. My school does not allow grade skipping even in the PG range. The fear is that if we let one we have to let them all.

So my thought is that if you have a PG child who needs major academic acceleration, you are more likely to get that in a lower area where the gifted kids really stand out.
But you have a MG/HG kid who can be challenged through enrichment and/or compacting, the higher level schools could be be a better fit socially & academically.

I wouldn't focus as strong on the State as much as I would the County.
