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? · design · r2
Operational item analysis of Spanish Math items administered during 2024–2025 (Tables 4.1–4.2). Mean p values increased over terms and "mean point-biserial correlations remaining constant at 0.32 across terms", with most items in the 0.2–0.4 discrimination range.
"Spanish Math items demonstrated a well-balanced difficulty distribution, with mean p values increasing from fall (0.48) to winter (0.51) and spring (0.52)"

- Spanish Reading items show gradually increasing mean p values and stable discrimination with no negatively discriminating items — related

- Benchmark items showed high mean difficulty and low item discrimination, with many trivial items and only one broken item — reports the opposite
- Spanish Math and Reading scores show high marginal reliability and moderate-to-strong test-retest stability, lowest for fall–spring and kindergarten — related
- Most Spanish test items show negligible differential item functioning across gender and Hispanic–White comparisons — related
