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? Schools in the lowest 5% of growth show dramatically varied achievement levels, and about 80% of spring achievement is accounted for by fall achievement with about 14% accounted for by fall-to-spring growth. → Andy Hegedus 2018

q2 · i? · associational · r2

Correlational analysis of growth and achievement in the MAP Growth school sample, plus a comparison of the 5% lowest-growing schools (growth percentile at or below the 37th in mathematics and 33rd in reading, Figure 2.8). The article reports "about 80% of spring achievement is accounted for by fall achievement, with about 14% of spring achievement accounted for by fall-to-spring growth," and that the lowest-growth schools' achievement varied dramatically.

"about 80% of spring achievement is accounted for by fall achievement, with about 14% of spring achievement accounted for by fall-to-spring growth."
