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? Convergence in kindergarten was not attributed to pre-K children's kindergarten classroom experiences. → Erik Ruzek 2020 q3 i? Convergence was instead attributable to preexisting individual differences, suggesting longer-term outcomes are shaped by factors outside early schooling. → Erik Ruzek 2020 (2)

q3 · i? · associational · r?

The study reports that "convergence in the groups’ performance in kindergarten was not attributed to pre-K children’s classroom experiences in kindergarten," ruling out kindergarten classroom quality as the explanation in this sample of 2,581 children.

"convergence in the groups’ performance in kindergarten was not attributed to pre-K children’s classroom experiences in kindergarten"

The authors report convergence was "attributable to preexisting individual differences" and found "support for the notion" that longer-term outcomes are impacted by factors outside the scope of early schooling, despite pre-K improving children's skills.

"Convergence was, however, attributable to preexisting individual differences, and there was support for the notion that even though children’s skills are susceptible to improvement as a result of pre-K, their longer-term outcomes are likely to be impacted by factors that are outside the scope of early schooling"
