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? Students initially retained who rejoined age-appropriate classmates showed no evidence of harm or substantial benefit in tested achievement, though the authors advise caution. → Nagaoka 2004

Evidence

Nagaoka, J., & Roderick, M. (2004). Ending Social Promotion: The Effects of Retention. Consortium on Chicago School Research. https://consortium.uchicago.edu/publications/ending-social-promotion-effects-retention

q2 · i? · causal · r2

Comparison of double-promoted students (over one-quarter of retained third graders and one-third of sixth graders in 1998-1999 rejoined their classmates) with summer-promoted peers found slightly higher third-grade gains and no sixth-grade differences; the authors call for cautious interpretation.

"While our results should be interpreted with caution, there is no evidence that these students' tested achievement in basic skills was harmed by their short-term experience of retention and their resultant lack of instructional time in the subsequent grade. There is also no substantial evidence of any benefit."
