In Dutch twin data, 61–91% of variance in Cito educational performance is attributable to genetic variance, 0–15% to shared environmental and 9–24% to non-shared environmental variance, depending on the assumed genetic relatedness of same-sex twins¶

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? The unmoderated ACE variance decomposition ranges from 61–91% genetic, 0–15% shared environmental, and 9–24% non-shared environmental variance across rSSG values of 0.70, 0.75, and 0.80. → Kim Stienstra 2024

q2 · i? · associational · r3
Unmoderated ACE decomposition (Table 1) of Cito scores for 29,434 twin pairs, run under three assumed same-sex twin genetic correlations (0.70, 0.75, 0.80) because zygosity was unknown. The article prints: "61– 91% of the variance in educational performance can be attributed to genetic variance".
"Altogether, 61– 91% of the variance in educational performance can be attributed to genetic variance, 0– 15% to shared environmental variance, and 9– 24% to non-shared environmental variance."
Discussion¶
Related Claims¶
- Moderation findings are sensitive to the assumed genetic relatedness of same-sex twins: no school-quality moderation at rSSG 0.75 or 0.80, and the gene-SES moderation holds at 0.75 but not 0.80 — related
- School quality is positively but weakly associated with Cito performance (b = 0.61, β = 0.06), much more weakly than parental SES (b = 2.89, β = 0.30) — related
- School quality does not moderate genetic and shared-environmental influences on educational performance once moderation by school SES and parental SES is considered — related
- Delaying definite tracking is associated with a larger genetic influence and a lower shared-environmental influence on secondary educational attainment among Dutch twins — related
