Students with mental health needs, behavioral support needs, and/or emotional disturbance can engage in internalizing behaviors, externalizing behaviors, or both. Preservice and induction phase elementary general education teachers are reported to have limited education in providing evidence-based behavior management strategies, especially for students who engage in internalizing and/or externalizing behaviors. There is little understanding as to the differences in elementary general education teachers' knowledge, application, and self-efficacy in applying evidence-based behavior management strategies between preservice teachers, first-year teachers, second-year teachers, and third-year teachers. The purpose of this preliminary secondary data analysis was to examine differences in U.S. elementary general education teacher knowledge, application, and self-efficacy in evidence-based behavior management strategies from preservice to induction phase teaching. Results indicated third-year teachers had significantly less behavior management knowledge than preservice teachers. All other results were nonsignificant; however, there were practical differences when comparing the four groups on the knowledge and application measures. Implications for findings indicate the need for induction programs to focus on evidence-based behavior management strategies to support the development of behavior management for induction phase elementary education teachers as they progress through their first 3 years of teaching.
