Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? School-level analysis found important variation in performance, with 3 of 9 charter schools significantly outperforming their local TPS alternatives in both subjects. → CREDO 2020

q3 · i? · causal · r2
School-level analysis rolling VCRs from feeder schools up to a simulated TPS school as the counterfactual, using per-year learning impacts over the 2016-2017 and 2017-2018 growth periods; schools were included only with a sufficient number of tested students for reliable inference.
"Three out of nine charter schools showed significantly stronger academic progress than their local district options in both reading and math."
