Surely some can justify just about anything through analysis, but the constraints of this choice system were not particularly limiting. Schools meet minimal time and curricular conditions.
Schools feed children and teachers, and often provide health or mental health support.
Schools meet secular requirements and abide by church-state limits. Although there has been much discussion about capital costs, in truth those costs go far beyond bricks and mortar. This is why and how most Charter initiatives short-change the change agents. None cover most of these costs. And this is my strongest argument against stand-alone charter schools, because I think they exploit the innovators.
