q2 i? In the prior-year cohort, the EL-Non-EL ATL-REG mean gap grew from 13 points in fall 2018 to 35 points in spring 2019, and regression showed ELs expected to grow less in all domains, significant only for PD. → McCarthy 2020

q2 · i? · design · r2

Descriptive statistics and multiple regression on the 2018-2019 prior-year cohort (n = 141 with complete DRDP data). The article reports ELs were expected to grow less than Non-ELs in all domains, statistically significant for only PD, with tests appearing underpowered.

"the difference between ELs' and Non-ELs' mean ATL-REG scores was 13 points in fall 2018 and 35 points in spring 2019"

Discussion¶

Related Claims¶

• During the intervention year, EL preschoolers' DRDP scores were predicted to increase more than Non-ELs' scores in all five DRDP domains after controlling for pretest, with statistically significant differences in ATL-REG and PD — 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
• 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 — possibly the same claim (merge candidate)
