Teachers are tasked with not only delivering high-quality, evidence-based academic instruction, but they are also responsible for managing student behavior within the classroom and school. To manage these behaviors, teachers can use a variety of strategies that result in a range of outcomes on student and school-wide functioning. Although an overreliance on punitive strategies has been shown to worsen behavior problems, positive strategies and social-emotional learning (SEL) techniques are associated with more favorable outcomes for students' global functioning. In a sample of K–12 teachers (N = 111), we examined direct associations between teachers' use of behavior management techniques (i.e., punitive, positive, and SEL) and their self-reports of perceived school climate. Furthermore, latent profile analysis was used to identify teachers' behavior management styles and evaluate whether teachers' characteristics and perceived school climate predicted behavior management style. Findings not only replicate previous research examining direct associations between behavior management techniques and school climate, but also extend the theoretical understanding of teachers' behavior management approaches. Three profiles of teacher behavior management style emerged, including a (a) Moderate Proactive profile characterized by frequent use of positive strategies and SEL techniques and infrequent use of punitive strategies; (b) Moderate Reactive/Proactive profile characterized by moderate use of both punitive strategies and positive strategies, as well as slightly lower use of SEL techniques; and (c) High Proactive profile characterized by very frequent use of positive strategies and SEL techniques and very infrequent use of punitive strategies. Use of these profiles may enhance understanding of how school psychologists can support teachers' behavior management practices through consultation or professional development to promote effective school and classroom behavior management practices.
