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.

q1 i? Before this paper, studies had estimated only associations between entry age and growth, or causal effects on achievement at one or two points, leaving causal growth evidence a gap. → Angela Johnson 2020
