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? CCSPP schools significantly improved standardized math scores by 0.06 SD compared with matched schools, equivalent to roughly 43 additional days of learning; the report prints no standardized effect size statistic for this contrast. → Swain 2025

Evidence

Swain 2025

Swain, W., Leung-Gagné, M., Maier, A., & Rubinstein, C. (2025). Community schools impact on student outcomes: Evidence from California. Learning Policy Institute. https://doi.org/10.54300/541.498

q3 · i? · causal · r2

Matched difference-in-differences analysis of first-cohort CCSPP schools versus matched comparison schools reports significantly improved math scores of "0.06 SD", described as "roughly equivalent to 43 additional days of learning"; comparison schools showed declines in the same period. No d, g, or other standardized effect size statistic is printed, so impact is null.

"and significantly improved standardized test scores in math (0.06 SD), roughly equivalent to 43 additional days of learning."
