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? Positive, statistically significant EPT results held across sensitivity analyses varying matching methods and the types of students included. → Anthony B. Fong 2015

q3 · i? · causal · r2
Sensitivity analyses in the impact evaluation chapter varied the matching approach (including the number of matches per ERWC student and matching without replacement) and the analytic sample. The report finds "the positive, statistically significant results were robust to a number of different sensitivity analyses."
"In addition, the positive, statistically significant results were robust to a number of different sensitivity analyses. These sensitivity analyses included varying the methods used to match ERWC and non-ERWC students and varying the types of students included in the analytic sample."
Discussion¶
Related Claims¶
- ERWC students gained more than matched non-ERWC students on the EPT (ES +0.13) — related
- In the grade 12 quasi-experimental evaluation, there was no statistically significant difference in achievement between ERWC and comparison students for either the Non-PT ICA or the PT ICA sample — related
- Meta-analytic estimates are robust to the assumed within-study effect size correlation in sensitivity analyses — related
- Assignment to the ERWC 3.0 in grade 11 produced a positive, statistically significant impact on achievement on the Non-PT ICA, but no statistically significant impact on the Summative Assessment sample — related
- The intervention effects on mathematics are robust across model specifications and did not differ between RCT and COVID-affected implementation contexts — related
