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.
q1 i? Preliminary models support the hypothesis that students most at risk (Tier 3) will experience the greatest growth in achievement after the introduction of City Connects at Grade 3. → Walsh et al. 2015

q1 · i? · causal · r1
Study 2 is a multi-level interrupted time series design with student-level fixed effects, currently being modeled in HLM, using teacher-rated report card scores in grades 1 through 5. The article states analyses are "still in progress" and that "Preliminary models support this hypothesis."
"Analyses are still in progress for this research question, but we expect that students most at risk (Tier 3) will experience the greatest growth in achievement after the introduction of City Connects at Grade 3. Preliminary models support this hypothesis."
