The aim of the current study was to examine mean‐group differences on behavior rating scales and variables that may predict such differences. Sixty‐five teachers completed the Clinical Assessment of Behavior–Teacher Form (CAB‐T) for a sample of 982 students. Four outcome variables from the CAB‐T were assessed. Hierarchical linear modeling was used to analyze variance components across three levels; examine mean‐group differences across outcome variables for student gender, race/ethnicity, and free or reduced‐price lunch status; and examine whether teacher variables predicted teacher‐specific differences in ratings. Results revealed that a significant amount of variance was attributable to teacher‐ and school‐level variables. Several mean‐group differences emerged, and some teacher‐specific differences in ratings across groups were predicted by teacher self‐efficacy for behavior management and teacher age, but not for teacher race/ethnicity, gender, or years of experience.
