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 In a school-level RCT in a large urban Texas district, students in Zearn schools significantly outperformed control students on the NWEA MAP, with larger effects for students not proficient at baseline (+0.13). → Zearn Math evidence review 2024

q3 · i1 · causal · r2
A school-level randomized controlled trial in a large urban Texas district across the 2022-23 and 2023-24 school years, with 64 schools randomly assigned and over 10,000 students in Grades 3-5. The review reports "significantly outperformed those in control schools on the NWEA MAP (effect size = +0.11 overall".
"Students in Zearn schools significantly outperformed those in control schools on the NWEA MAP (effect size = +0.11 overall; +0.13 for students not proficient at baseline)."
