q2 · i? · causal · r2

In the quasi-experimental study reviewed by the WWC, the significant positive ELA effect was limited to first-year CST scores for Cohort 3. The WWC characterizes the domain finding as a potentially positive effect based on a small extent of evidence.

"Herman et al. (2012) reported statistically significant positive effects of attending a Green Dot Public School on CST scores in English language arts during the first year of high school for students who started ninth grade in Green Dot Public Schools in 2009–10 (Cohort 3)."

The reviewed study found, and the WWC confirmed, "no statistically significant or substantively important effects" on third-year CST ELA scores for Cohorts 1 and 2, and likewise no significant effects on the Year 2 CAHSEE ELA scale score. Equivalence was not tested.

"The authors reported, and the WWC confirmed, no statistically significant or substantively important effects on CST scores in ELA during the third year of high school"
