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? When teachers' previous evaluation ratings were added to the statistical models, much of the principal-observer rating variation disappeared and the high-end difference was no longer statistically significant. → Sartain 2011

q2 · i? · associational · r3
Statistical re-analysis of the matched ratings showed that after controlling for prior checklist evaluation ratings, "much of the variation between principal and observer ratings disappeared," and the high-end difference "is no longer statistically significant." The authors offer two interpretations: principals may use historical knowledge or may rate more accurately.
"When we took into account teachers' previous evaluation ratings in the statistical models, much of the variation between principal and observer ratings disappeared."

Related Claims¶
- Principals and trained external observers gave aggregate-consistent Danielson Framework ratings in matched observations — related
- Principals inflated ratings at the high end of the scale, more often identifying instruction as distinguished than observers — related
- Variation across schools in principal-assigned professional practice ratings suggests principals' standards may not be fully consistent across schools — related
- Principals rated some instruction components inconsistently, rating communicating with students, using assessment in instruction, and organizing physical space lower than observers, and student engagement higher — related
- Principals rated teaching practice reliably at the low and middle ends of the rating scale, and most principals' severity matched trained observers — related
- Principals were far more likely than trained external observers to rate the same instruction Distinguished rather than Proficient — related
