Longitudinal item-fit analysis across fall, winter, and spring 2024–2025 (Table 4.3). About 7% of Math items and about 1% of Reading items misfit in one term; "items that show misfit in two or more terms are likely in need of review and recalibration."
"The vast majority of items, 91% for Math and 98% for Reading, show no misfit during any term."
