Being competent in managing online classes through the different qualities of the instructors incorporating active teaching and learning and technological capacities are important during the implementation of flexible schemes as a result of the educational reform amidst pandemic. With this, the researchers focused this study on determining the level of competence of the instructors in one institution in handling flexible teaching modalities and how it influences the engagement and satisfaction of the students in learning the lessons. Descriptive and correlational research designs were used having 133 randomly selected students from three different colleges in criminal justice education, computer students and teacher education. There were three sets of adopted instruments used answered by the students enrolled in a certain course handled by the researchers during 2020-2021 academic year. As observed by the students, their teachers are highly competent in establishing active learning, administration/ leadership, active teaching/ responsiveness and technological aspects in the delivery of flexible teaching and learning. When the teachers are highly competent in doing their task, students on the other hand are highly engaged and satisfied to different aspects involved in the flexible learning. As a result, there is a positive significant relationship depicted between teachers‟ competence and students‟ engagement. Similarly, positive significant relationship was obtained between teacher‟s competence and students‟ engagement in flexible teaching and learning. Moreover, when teachers were able to establish active learning and technological competence in their classes it predicts high engagement among their students. Lastly, when there is active learning and teaching as well planned by the teachers it predicts more satisfied students in the administration of flexible schemes of learning the tasks
