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? In top-quartile schools more than half of teachers describe moderate program coherence with another 15 percent noting strong coherence, while relatively few (32 percent) see little or no coherence; in bottom-quartile schools just over half describe little or no coherence although 44 percent report strong or very strong coherence. → Anthony Bryk 1997

q2 · i? · associational · r1
Descriptive quartile comparison from the Program Coherence scale summary, which assesses whether teachers believe school programs are coordinated with one another and consistent within and across grade levels. The report also notes bottom-quartile schools show 44 percent strong or very strong coherence. No significance test is reported.
"In the top quartile schools more than half of the teachers describe moderate program coherence, with another 15 percent noting strong program coherence in their school. Relatively few teachers (32 percent) consider these schools to have little or no coherence."
Discussion¶
Related Claims¶
- In bottom-quartile schools the School Improvement Plan is largely not implemented, with most teachers negative or mixed — related
- Joint problem solving distinguishes top- from bottom-quartile Chicago high schools: half of top-quartile teachers describe strong processes plus 13 percent very strong, while bottom-quartile teachers most often describe weak processes (46 percent) — related
- More than half of teachers in bottom-quartile schools describe little or no program coherence — possibly the same claim (merge candidate)
