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? Tutoring programs consistently outperform common alternatives such as class-size reduction and summer school, with effect sizes exceeding the average impact of typical school-based programs. → Kirk Vanacore 2026
