Students attending publicly funded, privately run charter schools posted slightly higher learning gains overall in reading than their peers in traditional public schools and about the same gains in math, but the results varied drastically by state, according to one of the most comprehensive studies of U.S. charter schools.
The study [PDF], published Tuesday by the Center for Research on Education Outcomes at Stanford University, found that charter students in Rhode Island, for example, gained the equivalent of an additional 86 days of reading comprehension and 108 days of math comprehension annually compared with peers in traditional public schools. In Nevada, however, charter students had 115 fewer days of learning in reading and 137 fewer in math annually, the study found.
Overall, the new study found that charter students gained an additional eight days of reading, while the math gains were identical. Low-income Hispanic and African-American students did much better in charters than their peers in the traditional school option, while white children did worse in charters.
The researchers and some charter proponents said the results suggest some states need to be more particular about which groups they award charters, and more aggressive about shutting low-performers.
According to the 26-state study:
- Students in poverty, black students, and those who are English language learners (ELL) gain significantly more days of learning each year in both reading and math compared to their traditional public school peers. Performance differences between charter school students and their traditional public school peers were especially strong among black and Hispanic students in poverty and Hispanic students who are ELL in both reading and math.
- Charter school enrollment has grown among students who are in poverty, black students, and Hispanic students.
- The 11 new states added marginally to the mathematics gains seen since the 2009 study, but more so to gains in reading.
