Professional development (PD) is known to be one pathway to expand teachers' knowledge and delivery of evidence-based transition practices, yet minimal research exists investigating what PD activities are most effective at increasing teachers' use of EBTPs. OBJECTIVE: The purpose of this studywas to determine howtransition specific PD influenced secondary special educators' knowledge and perceived self-efficacy regarding the use of EBTPs in their classrooms to support students with disabilities. METHODS: A correlational research design was used to investigate teacher self-efficacy to deliver EBTPs when the amount, type, and location of PD are factors. Descriptive statistics, an analysis of variance (ANOVA), and a multiple linear regression analysis were performed. RESULTS: The amount of PD offered had a significant effect on teachers' perceived efficacy compared to the location and type of professional development received. Further, the results of teachers' perceived effectiveness, changes made as a result of PD, and other factors related to PD are reported. CONCLUSIONS: After receiving PD, teachers were more likely to make changes in their classroom that, in turn, affected their self-efficacy and effectiveness to deliver EBTPs to support students with disabilities. Implications for teacher professional development research, practice, and policy are also discussed. 收起
