q2 · i? · causal · r2

Quasi-experimental propensity score stratification analysis of a cross-state sample of students, using multilevel models to balance key covariates between treatment and control groups. The study finds "charter school students perform consistently better on standardized mathematic achievement measures" with modest differences; no effect size is printed.

"We find that charter school students perform consistently better on standardized mathematic achievement measures, and some students grow faster than their traditional public school peers, although the differences are modest."

• South Carolina charter students show similar reading growth but weaker math growth than traditional public school peers, with a math disadvantage of 53 fewer days of learning per year — reports the opposite

• About 30 percent of South Carolina charter schools outperform traditional alternatives in reading and 15 percent in math, while 22 percent and 33 percent underperform — reports the opposite
• Virtual charter schools show far lower achievement, with students losing the equivalent of half a year of learning in reading and a full year in mathematics — reports the opposite
