The Center for Research on Education Outcomes at Stanford (CREDO) has been studying the results of public schools in cities around the country. In particular, its research looks at how much academic growth charter school students achieve compared to students with similar demographics statewide.
CREDO translates the impact of attending charter schools on students’ growth in reading and math into “additional days of learning.” For example, charter school students might make 10 additional days’ worth of math progress (in a school year of 180 days) compared to their peers.
In summer 2022, CREDO released results for San Antonio — and they are extraordinary. The study underscores that public charter schools provide high-quality educational opportunities for students. Children from all backgrounds are making remarkable academic progress.
