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? Under the study's projections, students are likely to return in fall 2020 with 37-50% of the learning gains in math relative to a typical school year, a larger projected loss than in reading. → Kuhfeld 2020

q2 · i? · associational · r2

The projection analysis reports students returning "with 37-50% of the learning gains in math," a lower retained share than the 63-68% projected for reading. No effect size is printed for this projection.

"students are likely to return in fall 2020 with approximately 63-68% of the learning gains in reading relative to a typical school year and with 37-50% of the learning gains in math"
