This study used item response theory (IRT) to derive sets of maximally efficient items (SMI) for a brief behavior rating scale (BBRS) from a common universal screening tool (i.e., the Social, Academic, and Emotional Behavior Risk Screener--Student Rating Scale [mySAEBRS]). We also evaluated the change sensitivity of these items for potential use in progress monitoring. Data from over 24,000 students (47% female; 40% White; 17% African American; 7% Hispanic) in Kindergarten through 12th grades were included in the first phase of analyses. A subsample of 774 students (43% female; 33% White; 3% African American; 0.5% Hispanic) was included in the change sensitivity analyses. Results suggested 3 items from each of the SAEBRS subscales (Social Behavior, Academic Behavior, and Emotional Behavior) could be considered maximally efficient and psychometrically informative. Additionally, change sensitivity analyses across the SMIs offered some evidence for the development of brief, 3-item standard BBRSs for use in progress monitoring students with social, academic, and emotional behavioral challenges. More research is needed to examine whether using BBRSs result in meaningful behavioral and social emotional change, particularly for specific demographic subgroups.
