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? Students in schools using PLC at Work scored significantly higher on the ACT Aspire math test than similar students in well-matched comparison schools, with an effect size of +0.08. → Professional Learning Communities at Work (PLC at Work) 2020

q2 · i? · causal · r2
A quasi-experimental study compared over 2,500 students in 12 Arkansas schools using PLC at Work to similar students in well-matched schools not involved in the initiative. The page reports "a statistically significant positive effect on the state-administered ACT Aspire math achievement test scores (effect size = +0.08)".
"PLC at Work had a statistically significant positive effect on the state-administered ACT Aspire math achievement test scores (effect size = +0.08), though it did not significantly affect ELA scores."

- A small set of mathematics-only studies gives existence proof that teacher participation in a mathematics PLC can enhance student learning, but evidence is insufficient to link formal assessment results to PLC participation — the general claim this finding bears on, with the studies behind it
