Q. How can we improve our preschools?
A. Ultimately, we need to get this nonsystem to behave more like a system, and we can start by establishing a uniform set of guidelines for every preschool. Everyone would benefit: It would give those who run the preschools a sense of how they can align their programs with the aims of the school system. It would give parents a tool so they could evaluate a program, and it would begin to ensure that every child is getting the early educational experience that he or she deserves.
