The above quoted data point is brought to you by DataFirst, which is owned by National School Boards Association, which is a lobbying arm of public state school boards associations.
I was curious to dig deeper into the above claim of charter vs. public school performance, but gave up last night when I could not find any non-biased data points.
Not surprisingly, public school lobbying arms claim state schools do better, while charter school association web sites proclaimed they do better.
The truth is that it probably varies, a lot, by specific school.
To me this is not an idle interest.
I would seriously consider moving my elementary grade school kids to a charter school if one was nearby (there isn't), and if I could be convinced that a charter school does a better job of educating then does our public school district. Alas, NY/NJ have 3-4% of students in charter schools due to low availability (not sure why, it's ~6% nationwide), and further 10-13% in private (mostly religious) schools, so the options are limited. We enjoy our kids company way too much to send them to a quality boarding school, never mind the cost.
