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.

q3 i? In ECLS-K difference-in-differences estimates using the number of years above the state threshold as the treatment, each year of a binding mandate increases math achievement by 0.572 points (2.7 percent of a standard deviation), reading by 0.470 points (2.0 percent), and science by 0.130 points (0.9 percent). → Frisvold David E 2015

q3 · i? · causal · r2

ECLS-K difference-in-differences specification replacing the binary above-threshold indicator with the number of years the school was above the state threshold (final rows of Table 7). The study reports the per-year estimates quoted above; no standardised effect size (d, g, r) is printed, so impact is null.

"Each year of attending a school with a binding state mandate increases math achievement by 0.572 points (with a standard error of 0.204) or 2.7 percent of a standard deviation, reading achievement by 0.470 points (with a standard error of 0.270) or 2.0 percent of a standard deviation, and science achievement by 0.130 points (with a standard error of 0.132) or 0.9 percent of a standard deviation"
