In the United States, many teachers feel underprepared to manage student classroom behavior positively. Such management is crucial for students to learn effectively, especially those with or at risk of emotional and behavioral disorders (EBD). Although increasing teacher praise and decreasing teacher reprimands may be research-based practices, more empirical evidence is required for them to be considered evidence based. The current study of 65 elementary school teachers and 239 students across three states contrasted the effects of these teacher behaviors on engagement and disruptions of students who were and were not at risk of EBD. Using structural equation modeling, we examined how the engagement and disruptions of students at risk were more sensitive to teacher praise and reprimand than the behavior of their typical peers. These results support the literature and invite teachers to consider that who they praise and reprimand is just as important as how.
