Claims

Achievement rank-order stability is high across primary school, with written-language stability (β = 0.62–0.75) exceeding mathematics stability (β = 0.38–0.45)

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.

q3 i? Autoregressive effects showed high rank-order stability of achievement across grades 1–4, stronger for written language than mathematics. → Kulakow 2023

Evidence

Kulakow 2023

Kulakow, S., Mahlau, K., & Kocaj, A. (2023). The longitudinal relationship between internalizing and externalizing behavioral problems with academic achievement in elementary school. https://osf.io/cyqak/?view_only=37eade9dd7c142e88fe9bef9451c125e

q3 · i? · associational · r2

In the cross-lagged panel models (N = 461), autoregressive paths showed "stable autoregressive effects of standardized estimates ranging from β = 0.62 to β = 0.75" for written language and β = 0.38 to 0.45 for mathematics, all significant.

"we found stable autoregressive effects of standardized estimates ranging from β = 0.62 to β = 0.75. While the estimates were smaller for mathematical achievement (β = 0.38 to β = 0.45), they were throughout significant and indicated medium regression effects."
