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

Description of the study's two sets of analyses using Pennsylvania's statewide data on students and principals from 2007/08 to 2013/14: a stability analysis of "2,424 principals" and a predictive analysis of "123 principals", followed by simulation of each measure's accuracy.

"First, using data on 2,424 principals, the study assessed the extent to which ratings from each measure are stable by examining the association between principals’ ratings from earlier and later years. Second, using data on 123 principals, the study examined the relationship between the stable part of each principal’s rating and his or her contributions to student achievement in future years."
