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.
q3 i? About two-thirds of the total difference in observation scores and almost three-quarters of the difference in value-added scores is due to differences among teachers in the same school. → Jiang 2016

q3 · i? · associational · r3
Variance decomposition of 2013-14 CPS observation and value-added scores. In any given school there are teachers with very high, low, or average scores on both measures.
"About two-thirds of the total difference across teachers’ observation scores is due to differences among teachers in the same school; this is the case for almost three-quarters of the difference among teachers’ value-added scores."
Discussion¶
Related Claims¶
- Professional practice ratings, student surveys, and value-added measures each have the potential to differentiate teacher performance in Pittsburgh Public Schools — related
- Minority teachers' lower observation scores are largely attributable to school characteristics, and no race/ethnicity differences appear on value-added scores — related
- Variation across schools in principal-assigned professional practice ratings suggests principals' standards may not be fully consistent across schools — related
