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.
q2 i? No findings in the two studies met WWC group design standards for any adolescent literacy outcome domain other than comprehension, so effects on alphabetics, reading fluency, general literacy achievement, and writing outcomes are unknown. → other-domains-1

q2 · i? · quant-synthesis · r2
WWC review scope statement: the two qualifying studies reported findings only on comprehension outcomes; no other findings met WWC group design standards within any other outcome domain in the Adolescent Literacy topic area. This is an absence of qualifying evidence, not a measured null effect.
"The effects of ITSS are not known for other outcomes within the adolescent literacy topic area, including alphabetics, reading fluency, general literacy achievement, writing conventions, writing productivity, and writing quality."
