This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

Evidence

Cooperative Integrated Reading and Composition® 2010

Cooperative Integrated Reading and Composition®. (2010). WWC Intervention Report, Adolescent Literacy. What Works Clearinghouse, U.S. Department of Education. https://ies.ed.gov/ncee/wwc/InterventionReport/111

q2 · i? · quant-synthesis · r1

Systematic review (WWC Adolescent Literacy protocol, Version 2.0) computing improvement indices from two quasi-experiments meeting standards with reservations. The report states the "average improvement index for comprehension is +7 percentile points"; the improvement index is a percentile-rank difference, not a standardised effect size, so impact is null.

"The average improvement index for comprehension is +7 per-centile points, with a range of +3 to +11 percentile points across findings from two studies."
