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? After controlling for pretest scores, ELs' DRDP scores increased more than Non-ELs' in all five domains, significantly for ATL-REG and PD and non-significantly for SED, LLD, and MATH. → McCarthy 2020

q2 · i? · associational · r2
Multiple regression on DRDP scores from the 2019-2020 intervention year at Fairsite Preschool, each domain analyzed independently, comparing EL and Non-EL growth. The article reports "statistically significant for two DRDP domains (ATL-REG, PD)"; no effect sizes are printed, so no magnitude is reported.
"The results show that after controlling for each child's pretest scores, ELs' scores were predicted to increase more than Non-ELs' scores in all DRDP domains. The difference between ELs and Non-ELs was statistically significant for two DRDP domains (ATL-REG, PD) and was not statistically significant for three DRDP domains (SED, LLD, and MATH)."
Discussion¶
Related Claims¶
- Kindergarten-readiness gaps between ELs and Non-ELs narrowed during the intervention year after widening during the prior year, with significant between-year differences for ATL-REG, SED, and PD — related
- During the prior year before the intervention, EL-Non-EL gaps widened in all DRDP domains and ELs were expected to grow less than Non-ELs, significantly for PD only — related
- Intervention-year ELs reached higher DRDP developmental levels by spring than prior-year ELs, while Non-ELs showed no discernable difference or a slight prior-year advantage — related
