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.
q3 i1 Compared to children in Tier 3 programs, children in Tier 4 programs gained an additional 1.2–1.7 months of learning and development, and those in Tier 5 programs gained an additional 2.2–2.5 months, with effect sizes of 0.08 to 0.16 standard deviations. → Sussman 2022

q3 · i1 · associational · r2
Regression analysis of fall and spring DRDP scores for approximately 70,000 children in 1,700 QCC-rated programs, controlling for fall scores and demographics. The article reports effect sizes "ranging from 0.08 to 0.16 standard deviations" as "modest but educationally meaningful gains."
"From fall to spring of the given study year, compared to children in Tier 3 programs, children in Tier 4 programs gained an additional 1.2–1.7 months of learning and development, and those in Tier 5 programs gained an additional 2.2–2.5 months."
Discussion¶
Related Claims¶
- Children with disabilities showed larger gains in higher-tier programs than children without disabilities — a narrower finding that bears on this claim
- Multilingual learners gained more in higher-tier programs than non-multilingual learners, with Tier 5 gains of 2.6–2.8 additional months — a narrower finding that bears on this claim
- Children from all racial/ethnic groups were projected to gain more in higher-tier programs, but most racial/ethnic differences were not statistically significant — a narrower finding that bears on this claim
- Black, Hispanic/Latino/a, and Multiracial preschool children were underrepresented in higher-quality (Tier 4 and 5) programs — related
