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? Distributions of 2014 reading scores in B, C, and D schools were nearly identical, and many students in D and F schools scored as high as students in A and B schools. → Adams 2017

q2 · i? · theoretical · r2
Analysis of Oklahoma student reading score distributions plotted by A–F letter grade (Figure 2), adapted from the authors' 2015 report to the Oklahoma State Department of Education, shows within-grade distributions resembling the state population distribution.
"Distributions of reading scores in B, C, and D schools are nearly identical. F schools had more low-performing students than the population, but arguably, the distribution of reading scores is not much different than that of the population."

Related Claims¶
- Percent meeting standards is an imprecise metric whose cut-score concentration produced the Era 2 misconception that Chicago taught basic skills better than high-level skills — related
- Low and Growing states have nearly identical average math scale scores, but students in Low states are more likely to improve or maintain grade level (64% vs. 60%) — related
- Oklahoma achievement declined rather than grew across 2012–2014 under the A–F letter grade system, with the largest drops in F schools — related
- Composite accountability indicators such as A–F letter grades fail to capture the cognitive and noncognitive competencies of deeper learning and college and career readiness — a broader claim this one bears on
- In Oklahoma A and B schools, FRL students scored lower in reading than Non-FRL students, with the gap widening in 2014 — related
- Group averages are misleading when applied to individual pupils because of extensive overlapping in weight and height across grades — related
