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.

q1 i? The model estimates each school's effect on student performance across all tested grades and subjects while accounting for student mobility, observable demographic differences, and measurement error in test scores. → Kevin Booker 2008
