This article examines developing student-centered teaching and learning at school. The personality of a teacher is a complex structural formation, representing a system of values, meanings of life and professional activity. It is relevant and significant to study the abilities of a teacher as a subject of his own professional activity, which involves the relationship and interdependence of qualitative changes in the personality of the teacher himself and in the personality of his students, taking them into account when assessing the professionalism of a teacher. A future teacher has his own set of personal and professionally important abilities and qualities that make up personal and professional potentials, which are prerequisites for his success in his work.
