I can imagine situations in which homeschooling would be so appealing if there was no assistance from the schools. In PA, the mandate is a nice place to fall back on, but you are still reliant on the good will of administrators because there isn't any real teeth in the law. Luckily, we found good will.
As someone who interviewed all over the country in the last year with HG schooling high on my priority list, there seemed to be massive differences in how states approach this. I interviewed multiple places in a state with separate, self-contained, HG programming in every place I looked. This state has a mandate with funding and clearly some commitment to GT kids, at least in theory. I looked at another state with a great education record in general and all I got was "all our kids are gifted." I looked at multiple districts in PA and some had programs worth having and some had "all our kids are gifted." There are states who seem committed to this, some states who seem indifferent who have districts committed to effective GT programming, and some areas I looked at who seemed to find the whole thing elitist and offensive.
What angered me about looking at various locations was how easy it seems to create decent programs in any medium sized city or above. I've seen small suburb locations with decent self-contained options for HG kids and massive school districts for major cities with nothing of any value. I don't believe that any fairly decent sized city can't run a self-contained HG classroom at little cost to the district, but there aren't that many of them in my research.
Whether the HG program we're moving to delivers or not is yet to be determined . . . . .

, but I'm hoping and hoping . . . .
