The effect of teaching models, teacher training programs, and teaching evaluation approaches on the teaching competence of vocational educators at colleges and universities is investigated in this paper. Since vocational education is so important in arming students with industry-relevant skills, knowledge of the elements improving teachers' capacity for instruction is vital. This study looks at how various teaching approaches affect instructional effectiveness, the function of teacher training programs in skill development, and how teaching evaluation approaches support ongoing development of teachers. The study also investigates the moderating effect of institutional support, determining whether chances for professional growth, administrative support, and resource availability either enhance or diminish these links. Through an analysis of these interactions, the study hopes to shed light on how best to maximise occupational education programs so that teachers are ready to fulfil changing industry needs and improve student learning results.
