q3 · i? · causal · r?
The article reports a family-background moderator: the entrance-age association is “especially pronounced among children from upper-income families.” The authors link this to greater pre-kindergarten skill accumulation in those families, consistent with their prior-skills interpretation. No effect size is printed in the available text.
"The association between achievement test scores and entrance age appears during the first months of kindergarten, declines sharply in subsequent years, and is especially pronounced among children from upper-income families, a group likely to have accumulated the most skills prior to school entry."
Discussion¶
Learner Variables¶
