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? When the top and bottom 5% of schools are reselected on fall achievement, students in the bottom 5% mathematics schools tended to grow worse, whereas average growth between top and bottom 5% was similar in reading, with more bottom 5% reading schools growing students significantly better or worse. → Andy Hegedus 2018

q2 · i? · associational · r2

Observational re-analysis selecting top and bottom 5% of schools on fall achievement and comparing growth distributions (Figure 2.7). The article reports that in mathematics "students in the bottom 5% achieving schools tended to grow worse," while in reading average growth between top and bottom 5% was similar, with more bottom 5% schools growing students significantly better or worse.

"In mathematics, students in the bottom 5% achieving schools tended to grow worse, as shown in Figure 2.7. The average growth between the top and bottom 5% was similar in reading, with more bottom 5% schools growing students significantly better or worse than the top 5% achieving schools."
