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? Elementary cohort achievement was consistently higher than the state average in four of nine MiC districts (Garden Grove, Elk Grove, Long Beach, and San Francisco) and consistently lower in four others (Dinuba, Oakland, Oceanside, and Santa Ana). → Perry 2019

q2 · i? · associational · r2

Student-level cohort analysis (Table 4) following individual students across grades 3–5 in nine MiC districts shows scale-score gains generally reflecting the statewide growth pattern; the authors suggest stronger 2015 baseline performance may reflect pre-baseline conceptual-mathematics efforts.

"Student achievement for the elementary school cohort across 2015–2017 was consistently higher than the state average in four of nine districts (Garden Grove, Elk Grove, Long Beach, and San Francisco)."
