Jack Elbaum on recent studies that show charter schools in the United States have higher academic success rates than ordinary state-funded schools, despite a significantly lower funding rate:
If you thought charter schools received anywhere near the same amount of funding as traditional public schools, then think again.
A new, massive study from the University of Arkansas finds that “On average, charter schools across 18 cities in 16 states (…) receive about 30 percent or $7,147 (2020 dollars) less funding per pupil than traditional public schools.” Over the past two decades, this funding disparity has remained relatively stable.
The gaps are, predictably, more severe in some places than others. The study notes that “Atlanta has the largest percentage-based charter funding disparity (about 53 percent), while Camden has the largest disparity in dollars ($19,711). Houston has the smallest disparity in terms of percent (three percent) and dollars ($417).”
Importantly, the regression analysis run by the authors did not suggest differences in the proportion of students in poverty or English Language Learners are the reason for the disparity. However, it did find that after taking into account differences in the number of special needs students, the disparity dropped considerably — although it remained significant ($1,707).

Based on these data alone, it would not be unreasonable for one to expect that these charter schools had worse educational outcomes than their traditional public school counterparts.
The only issue is that this is not the case.
A recent study from Stanford University, for example, found that charter school students gain 16 days’ worth of reading and six days of math per year relative to those in traditional public schools. These benefits were particularly pronounced among minority students who were also in poverty. Education Week reported that “Black charter students in poverty gained 37 days of learning in reading and 36 days in math over their counterparts in traditional public schools, and Hispanic students in poverty gained 36 days of reading and 30 days of math over their traditional public school peers.”
Economist Thomas Sowell’s 2020 book Charter Schools and Their Enemies also offers compelling data suggesting the efficacy of charter schools. He studied a set of charters and traditional public schools in New York City that served essentially identical populations. In many cases in the study, a charter school and traditional public school would even occupy the same building.
