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 i? Borman et al. found a statistically significant positive effect on CST-ELA, while Hill and Lenard's two-year LevelSet Lexile average was neither statistically significant nor substantively important. → What Works Clearinghouse 2018

q3 · i? · review · r3
WWC review of two studies including 32,110 students: Borman et al.'s quasi-experiment showed a statistically significant positive CST-ELA effect (domain effect size 0.04, improvement index +2), and Hill and Lenard showed a significant positive LevelSet effect in spring 2015.
"Hill and Lenard (2016) reported, and the WWC confirmed, a statistically significant positive effect of Achieve3000® for students in grades 2–5 on the LevelSet Lexile score in spring 2015."
