Subclaims¶
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? The first national randomized study of the impacts of charter schools on student achievement examined charter school effects on achievement. → Melissa A. Clark 2011
