Creativity in teaching is a very topical issue and as such can be included in the very important goals of learning in the 21st century. It is important on an individual, social and global level. Without creative individuals there would be no innovation, development of science, art or literature. The school should be a place for encouraging and developing students' creativity. Unfortunately, this is not always the case, and a large number of creativity schools do not attach the importance they should. Teachers play a very important role in developing all components of student creativity. Teachers need to be creative as well because through their own creativity they encourage the development of the creativity of their students. But creative teachers are more exception than rule. Creative students are a burden to a large number of teachers, not a gift. For this reason, the process of educating teachers is extremely important, as teachers are able to stimulate the creativity of the pupils only with the development of personal creative potential. It is that each student has the potential, is potentially creative, only that creativity must be able to stimulate. This thesis work will try to explain the concept of creativity, to point out its importance and to present a strategy for the development of pupil's creativity. Since the increase in creativity in teaching begins with the teacher, it will be attributed to the competences of a creative teacher. Namely, teachers can not recognize the importance and the advantages of creative teaching if they have not experienced it themselves. In addition to the competences of creative students and teachers, it will explain how to measure and evaluate the process of creativity and give some ideas to include it in the content of the subject.
