A maturing charter sector still operates on first-generation laws designed to launch a few experimental schools. However, the charter sector has moved beyond this initial launch stage of its development. The new focus on scaling quality and the growth of managed networks has placed particular demands on old policies, practices, and authorizing capabilities. Growth in online and blended learning, interest in high-level STEM, and conversions and turnaround are additional new pressures on the one-size-fits-some process. States should update authorizing laws to incorporate multiple pathways and new capacities that refl ect the realities of the charter landscape, and take advantage of emerging opportunities to add quality educational options.
