In some cases, CommonLit’s IRT (Item Response Theory) scoring methods require presenting a range of potential scores for students that achieve the highest possible score on an assessment. This means that if a student scored the highest possible score on that assessment, their ability level lies somewhere between the highest score on that assessment and the highest possible scaled score (e.g., a score between 245-250).
