The thesis deals with the function of a teacher's assistant in a primary school. The work is divided into theoretical and practical part. In the theoretical part, I focus on inclusive education, which is related to students with special educational needs. The second chapter of the theoretical part deals with the teaching assistants, their qualification, and personal prerequisites. I also deal with the role and activities of assistants in primary school and their job. The third part is devoted to cooperation between teachers and assistants. I present the possible benefits and risks of this cooperation. Due to the current epidemy of coronavirus, I focused the practical part on the cooperation between assistants and teachers during distance learning. I used the method of semi-structured interviews. The results of my research show that each cooperation was handled differently. Most teachers are aware of the benefits of this cooperation and have involved and collaborated with assistants even during distance learning, during which the assistants acted not only as support for kids with SEN. Key Words Assistant teacher, inclusive education, primary school, cooperation between teacher and assistant teacher
