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? The study did not find statistically significant effects of Reading Apprenticeship® on the GRADE reading comprehension and vocabulary subtests for Cohort 1 students, nor on the GRADE vocabulary subtest for Cohort 2 students. → What Works Clearinghouse 2010

Null findings from the randomized controlled trial's first cohort (686 intervention and 454 control students).
