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? A one standard deviation increase in school closure duration (47 days) is associated with a 0.04SD larger decrease in average civic knowledge. → Kennedy 2026

q2 · i? · associational · r3

Separate regression model from the same fixed-effects analysis of ICCS 2016/2022 data. The article reports longer closures "are associated with greater declines in average civic knowledge", with a coefficient slightly more negative than the stringency one, though not significantly so.

"The relationship implies that an increase of school closure duration by one standard deviation (47 days, approximately 9 school weeks) would be associated with a 0.04SD larger decrease (or 4-points on the ICCS scale) in average civic knowledge scores for a country."
