The article is devoted to the formation of professional competencies in chemical education. in the preparation of bachelors in chemistry 04.03.01 (Profile environmental chemistry, chemical expertise and environmental safety), the authors pay special attention to the formation of chemical and ecological competence, which is seen as the result of education, manifested in the ability and readiness of graduates to use their chemical knowledge and skills and value relationship to address various environmental problems and challenges. Purpose of the article - to show the experience of the implementation of the competency approach in training bachelors- chemists developed based on the theoretical model of chemical and ecological competence. the authors developed a structural and functional model of the formation of chemical and environmental competence in the direction of bachelor 04.03.01 chemistry, which includes the purpose, content, organizational and methodical and effective evaluative components. a substantial component of the structural-functional model comprises two parts: an invariant chemical (system of fundamental chemical knowledge and skills in accordance with the program of each chemical disciplines) and variable integrative chemical and environmental part. these two parts create the basis for the formation of general and professional competences, specified in the work programs of each discipline. represented by the structural and functional model served as the basis for orienting development of methodical maintenance programs at the department of chemistry, huge public alarm.
