Baseline multigroup model comparison in Results for basis coefficients (shape of growth): Δχ2 (12) = 19.84, p = .070. The article reports the shape of growth did not differ across the three EF groups; no effect size is printed.

"The constrained basis coefficient model fit the data equally well, evidenced by model fit statistics and chi squared difference tests (χ2 (108) = 137.23, p = .030; AIC = 13673.77; aBIC = 13688.67; CFI = .96; TLI = .97, ∆χ2 (12) = 19.84, p = .070) suggesting that the shape of growth did not differ across the three EF groups."

Discussion¶

Related Claims¶

• With covariates, early and intermediate EF groups become indistinguishable in math level and growth, but the later EF group's disadvantage remains — related
• Early EF developers start pre-k with higher math levels than intermediate and later developers and maintain that advantage over time — related
