Operational item analysis of Spanish Reading items in 2024–2025 (Tables 4.1–4.2). The report states "The absence of negatively discriminating items supports that Reading items reliably measure the intended construct"; most items fell in the 0.3–0.6 p-value range.

"Spanish Reading items also showed an increase in mean p values from fall (0.44) to winter (0.46) and spring (0.48), indicating a gradual increase in the proportion of correct responses over time"
