Such programs are indeed great, if you happen to live someplace where they exist. If a student is unfortunate enough to live someplace where they don't, the districting policies, at least here, prevent students from crossing district boundaries to enable them to receive such programs, assuming of course there is a district reasonably near that has it. Under the current system, students only have access to those programs the district can afford or get people for. Even if there is a better district nearby, students are not allowed to cross the boundaries (maybe not in all cases) to seek education better suited to their needs.
Locally, we have severe problems with the boundaries, they are not allowed to cross county lines. As a result, students within a few miles of 3 different schools are forced to ride the bus for up to 5 hours a day or more to go to the school in their district/county. This also occurs, at some level but not that extreme, near state borders.
While independent, decentralized education does allow for the existence of a greater variety of methods of education, it is only a positive if the students are allowed to seek the one that best suites their needs. Otherwise, you get parents staring across the fence at an outstanding school district while be forced to send their kids to a poor/mediocre system. While it is easy to say, well move, this is not always an option. Locally, two pieces of property adjoining each other but on different sides of a county line, the one in the outstanding district has a property value 2-3 times greater than the one in the poor school district.
