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? Relative to students in neither sub-group, early starters outperformed by .11 SD in math and .15 SD in ELA, while chronic delayers underperformed by .13 SD in math and .11 SD in ELA. → Jordan Gutterman 2026

q2 · i? · associational · r2

Regressions with sub-group dummies (Table 3) on the 711-student sample: early starters (19.7% of sample) β=.11 (p=.07) math, .15 (p=.02) ELA; chronic delayers (19.4%) β=-.13 (p=.05) math, -.11 (p=.11) ELA.

"Early starters outperformed the baseline group of regular starters by .11 SD in math and .15 SD in ELA; the chronic delayers underperformed regular starters by .13 SD in math and .11 SD in ELA."
