Teacher self-efficacy (TSE) is related to teachers' job satisfaction, retention, motivation to improve, and work-related stress. Using data from the 2018 Teaching and Learning International Survey (TALIS), we investigated the impact of an innovative campus culture and preparation for teaching cross-curriculum skills on TSE. Data indicated that working at innovative campuses had small effects on TSE in classroom management [beta] = 0.12), instruction ([beta] = 0.06), and student engagement ([beta] = 0.17). Teachers' preparation to teach cross-curriculum skills had small to medium effects on TSE in classroom management ([beta] = 0.20), instruction ([beta] = 0.34), and student engagement ([beta] = 0.30).
