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? Correlations between Z-scores for short-term (single-year) and long-term (grades 2–6) school growth contributions are highest for third grade at roughly .095 in math and reading. → Soland 2019

q2 · i? · associational · r2

CP model analysis comparing within-year Z-scores to grades 2–6 growth Z-scores for the same schools, using a consistent student sample. Correlations were "highest for third grade with estimates of roughly .095" in both math and reading; no effect size beyond the correlation is printed, so impact is null.

"In math and reading, the correlations between Z scores for short- and long-term growth are highest for third grade with estimates of roughly .095. These results indicate that the gains attributable to schools within a single year are only tenuously associated with growth produced during elementary school."
