The study of professional deficiencies of vocational training teachers is implemented based on the competence approach, the concept of vocational education and the theory of professional deficits.

The groups of professional deficiencies of vocational training teachers in the field of methodical competence were identified (the use of modern forms and methods of organizing vocational and pedagogical training; the use of modern pedagogical, including digital technologies; creating conditions for the personal and professional students’ development; control and assessment).
