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? · associational · r?
Stability analysis of 2013/14 component measure ratings found "moderate to high year-to-year stability" for practice instrument ratings and growth percentiles, with growth percentiles less stable in smaller schools.
"Principal practice instrument ratings and school median student growth percentiles had moderate to high year-to-year stability. But school median student growth percentiles changed more across years in smaller schools than in larger ones."
Discussion¶
Related Claims¶
- Component measure ratings had low to moderate positive correlations with each other, suggesting the components measure distinct dimensions of principal performance — related
- School median student growth percentiles were stable year to year even when the school changed principals — related
- Insight survey domain averages are more stable across years when a school keeps the same leader, suggesting principals affect these measures — related
