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? The investigation of pre-K persistence and convergence examined children from low-income homes living in a large and diverse county, with a sample of 2,581. → Erik Ruzek 2020

The study's scope is stated in its abstract: it "examined the benefits of pre-K through the end of kindergarten for children from low-income homes who lived in a large and diverse county (n = 2,581)," also examining factors associated with a reduction in benefits.
"The present investigation examined the benefits of pre-K through the end of kindergarten for children from low-income homes who lived in a large and diverse county (n = 2,581)"
Discussion¶
Related Claims¶
- Convergence between pre-K graduates and nonattenders is largest for more constrained skills such as letter-word identification — related
- Pre-K graduates outperform nonattending peers in achievement and executive functioning at the end of kindergarten — related
- Convergence is attributed to nonattenders making greater gains in kindergarten than pre-K graduates — related
- Pre-K benefits at the start of kindergarten diminish by a little more than half during the kindergarten year — related
- Kindergarten convergence is not attributable to pre-K children's kindergarten classroom experiences but is attributable to preexisting individual differences — related
- NC Pre-K participants made greater gains than expected for normal developmental growth, with particular benefits for dual language learners and low-income students — related
- Early childhood education programs often yield larger benefits for children most in need, such as low-income children, children of color, and those with fewer educational resources — a broader claim this one bears on
