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? Measures of promotion power substantially reduce or even eliminate the relationship between students' poverty and the school's measure of performance, assessing school effectiveness more accurately. → Jonah Deutsch 2020

q2 · i? · associational · r?
Key finding from the Mathematica study of Louisiana public high schools, which used statistical modeling of statewide administrative data. The report states promotion power measures "substantially reduce or even eliminate the relationship between students’ poverty" and performance ratings. No effect size is printed.
"Measures of promotion power substantially reduce or even eliminate the relationship between students’ poverty and the school’s measure of performance, thereby assessing school effectiveness more accurately."
Discussion¶
Related Claims¶
- Heavy weighting of achievement data in U.S. school evaluation clouds how much learning is actually occurring, particularly in high-poverty communities — related
- Student background characteristics are less strongly related to promotion power scores than to status measures — a narrower finding that bears on this claim
- Growth measures offer a clearer, more accurate picture of learning than achievement data, while achievement data remains critical for tracking student progress — related
- Schools positively impacting one promotion power measure are more likely to positively impact other long-term outcomes, but many show varying effectiveness across outcomes — related
