This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? School median student growth percentiles exhibit year-to-year stability even when the school changes principals, which may reflect persistent school characteristics rather than the individual principal. → Christine Ross 2015

q2 · i? · associational · r?

Observational analysis of pilot data on school median student growth percentiles. The report finds "year-to-year stability even when the school changes principals" and attributes this, as an interpretation, to persistent school characteristics. No stability coefficient is printed on this page.

"School median student growth percentiles, which measure student achievement growth during the school year, exhibit year-to-year stability even when the school changes principals. This may reflect persistent school characteristics,"
