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? High schools with clusters of at least three national-board-certified teachers scored significantly higher on collective responsibility, reflective dialogue, and teacher-teacher trust; in elementary schools the trend was evident but not statistically significant, though NBCT-cluster elementary schools were more likely to use reformed literacy practices. → Hart 2006

q2 · i? · associational · r2

Cross-sectional comparison of schools with and without NBCT clusters using CCSR teacher survey measures of professional capacity. The elementary-level trend did not reach statistical significance, but elementary NBCT-cluster schools were significantly more likely to use reformed literacy practices.

"High schools with clusters of at least three national-board-certified teachers (NBCTs) scored significantly higher on several measures of professional capacity, including collective responsibility, reflective dialogue, and teacher-teacher trust."
