Over the past few decades, donors have poured millions of dollars into improving K-12 schooling by creating a new sector of public charter schools of choice that are accountable for results. One analysis calculates that 11,827 foundations have provided financial support to nonprofits in the charter schools category—money given not just through traditional grants but through program-related investments and social impact funds.
These donors—and charter supporters in general—have often been derided for their efforts. So has it been worth all the hassle and wrath directed at them? In short, yes. (Last week, I summarized research studies that show the salutary effect charter schools have on closing the achievement gap, reducing inequality between richer and poor students, and lifting the performance of entire school districts.) As economists Douglas Harris and Feng Chen write, “Charter school laws have been arguably the most influential school reform efforts of the past several decades.”
Since the first law creating these schools was passed in 1991, we’ve learned much about their positive impact on students, the traditional K-12 system, and the communities where they exist. I would summarize the three most important lessons like this:
These three lessons create what I call the virtuous improvement cycle of charter schools.
