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? Student performance in the 2021/22 school year was worse than in the two prior school years, and because at least 50% of norm sample test events came from 2021/22, the updated norms are heavily weighted toward pandemic performance; the updated norm group performed slightly lower than the previous norming group. → Wei He 2022

q2 · i? · associational · r2
Observational analysis of test volumes and average RIT scores by school year (Figure 3.1 and Table 2.2) across all seven subjects. The discussion adds that "the performance of the updated norm group was slightly lower than that of the norming group used in the previous study," so the same score is likely associated with a slightly higher percentile under the updated norms.
"While the test volumes in the 2021/22 school year hit record high for all subjects, student performance in that school year was worse compared with other two school years. Given that 50% of norm samples were from the 2021/22 school year, we would say that the norms of interest in this study were heavily weighted towards the 2021/22 pandemic performance."
