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. 

Key Findings

• Overall, San Antonio public charter school students achieved 51 more days’ worth of reading progress and 46 more days’ worth of math progress in one school year compared to statewide averages.

• In reading, English learners and special education students at San Antonio charter schools exceeded the progress of their peers statewide by about three months.  

• In math, Black students at San Antonio charter schools outpaced their peers statewide by the equivalent of 73 additional days of learning. 

• San Antonio charter school students across all subgroups, and in both subjects, made more academic progress than their Texas peers by at least one month’s worth of learning.
