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 i1 In the 286-participant effectiveness trial conducted by an independent research group with school-employed coaches, effect sizes ranged from 0.21 (small) to 0.67 (medium), with all differences significant. → Andy J. Frey 2023

q3 · i1 · review · r2
Four-year national effectiveness trial across 48 elementary schools in five U.S. states, with 24 schools randomized to each condition and 286 teacher-student-parent triads; coaches were school employees. The review reports a small ES of 0.21 on parent-reported SSiS-PB and a medium ES of 0.67 on teacher-reported SSiS-SS, with all differences significant.
"ESs across prosocial, PB, and academic engagement domains ranged from 0.21 (small; improvement index = +8.4) on the parent-reported SSiS-PB subscale to 0.67 (medium; improvement index = +24.7) on the teacher-reported SSiS-SS subscale."
