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? Studies offering certification after successful completion observed larger knowledge effect sizes (g = 1.39) than programs without certification (g = 0.86); certification did not influence other outcome categories. → Johanna L. Donath 2023

Moderator analysis of the certification design aspect across intervention studies in the meta-analysis. "larger effect sizes for knowl edge gain ( g = 1.39 [1.07; 1.72])" with certification; no influence on other outcome categories.

"Studies offering certification after successful completion of the program observed larger effect sizes for knowl edge gain ( g = 1.39 [1.07; 1.72]) t han did programs without certification ( g = 0.86 [0.65; 1.08]), but this did not influence the other categories of outcome variables"
