q3 i? Charter middle school students show math growth equivalent to 53 additional days of learning versus TPS virtual twins, while multi-level charter students have 24 and 77 fewer days of learning in reading and math. → CREDO 2019

Evidence¶

CREDO 2019¶

CREDO, Center for Research on Education Outcomes, Stanford University. (2019). Charter School Performance in South Carolina. https://credo.stanford.edu/reports/item/charter-school-performance-in-south-carolina-2019-2/

q3 · i? · causal · r2

Grade-configuration analysis comparing charter students in elementary, middle, high, and multi-level schools with their respective VCRs; elementary and high charter students showed similar growth to TPS in both subjects.

"Inferior progress is found among charter students enrolled in multi-level schools. When compared to their TPS virtual twins multi-level charter students are found to have 24 and 77 fewer days of learning than TPS VCRs in reading and math, respectively."
