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.

q2 i? One of two studies showed a statistically significant positive effect on social studies achievement while the other showed an indeterminate effect (average improvement index +5, range +1 to +9). → Knowledge Is Power Program (KIPP) 2018

q2 · i? · causal · r2

Two quasi-experimental studies with 10,363 students. The Tuttle et al. (2015, High School) social studies effect was "not large enough to be considered substantively important (that is, an effect size of at least 0.25)" and was characterized as indeterminate.

"the estimated impact of the intervention on outcomes in the social studies achievement domain was positive and statistically significant for one study, and neither statistically significant nor large enough to be substantively important for one study."
