2025 Norms
The easyCBM team at the University of Oregon updates our national norms every five years to ensure that interpretation of student performance reflects current grade-level expectations. Data from the 2024–2025 academic year were drawn from valid easyCBM school district accounts, with strict inclusion criteria applied to ensure score validity and consistency. A data selection process prioritized districts with comprehensive testing coverage, followed by stratified sampling to ensure geographic representation across four U.S. regions. The new norms reflect actual student performance on the easyCBM measures. In some cases, the percentile rank associated with a particular raw score increased; in other cases, it decreased. Such changes are to be expected when norms are updated and are a normal part of the norming process. Our next update will occur in 2030.
