Creativity and critical thinking are considered to be some of the most important competencies in the 21st century. They are both intertwined and dependant on each other. It is crucial to encourage and develop these competencies from an early age. Encouraging and developing creativity and critical thinking in children and young people can be done in various ways. The educational system, along with the parents, plays a big role in the development of these competencies. This research aimed to examine the attitude of primary school teachers towards the relationship between creativity and critical thinking during required reading lessons, taking into account their years of service. In order to achieve this goal, a qualitative research method was used – semi-structured interview. Fourteen respondents from different primary schools participated in this research – thirteen women and only one man. Additionally, the respondents differed in their years of service (from those with a few years of service to those close to retirement). The results obtained by this research show how teachers (regardless of their years of service) often use creative approach to reading, and they believe that it encourages the development of critical thinking. The primary goal of this research was to raise awareness of how important it is to develop creativity and critical thinking during required reading lessons. Finally, this research aimed to encourage teachers to use different approaches while delivering required reading lessons.
