Subclaims¶

q3 i? In a student-level RCT, assignment to ERWC had a positive and statistically significant impact on grade 11 achievement as measured by the Non-PT ICA, but no statistically significant impact was detected with the Summative Assessment sample. → Fong 2022

q3 · i? · causal · r2

Student-level randomized controlled trial in 17 schools in the 2020/21 Evaluation Year, with grade 11 students randomized by WestEd researchers to ERWC or a comparison English curriculum. The report states the impact was "positive and statistically significant" on the Non-PT ICA only; no effect size is printed in the quoted finding.

"The results of the grade 11 impact evaluation found that assignment to the ERWC has a positive and statistically significant impact on student achievement as measured by the Non-PT ICA; however, no statistically significant impact was detected with the Summative Assessment study sample."
