There is a debate among education professionals today regarding the definition of successful teaching, which focuses on the characteristics of such teachers. After much discussion (Grigg 2010), three characteristics have been defined: • charismatic teacher; • expert; • reflective. This debate is not only at academic levels, but its conclusions are important to evaluate the work of successful teachers. Let's look at these models briefly. The charismatic teacher Good teachers are often cited for their personality. They bring enthusiasm and passion for teaching to the classroom. They are cheerful and attentive to students. Often these teachers stand out for taking care of students, especially in delicate cases when they have behavioral problems or some other kind. They are long preserved in the memory of students and colleagues for their personality and it happens that many other teachers follow them as a model, therefore they imitate them in their profession and in life. The question of where 'good' teachers differ in personal qualities from those who are not as good has been examined by Morrison and Mclntyre (1969). The problem with the charismatic teacher model is that there is little mention of what the students have learned. These teachers stand out for their teaching methodology, explain well, recite nicely, qualities that are distinct from teachers who have other qualities. The expert teacher This is more about demonstrating the qualities of these teachers. They are quite good masters of the subject, illustrate well every aspect of it and influence its understanding in the students. They have good communication skills. Some researchers (Gipps et al. 2000; Wolf, 1995) seek to standardize the characteristics of these teachers, who serve as models, by formulating the competency model. Such teachers are difficult for others to match when it comes to their model of competencies, which they possess at a fairly high level. Expert teachers are usually also called competent. Competence is a broad concept, it describes the ability that someone has to demonstrate in a given occupation. The competence is related to the general qualities of the demonstration of some qualities which are evaluated according to the expected results, for which the formulation has already been made. Competencies include knowledge, habits and values.
