Introduction: This survey aimed to assess and compare the views of primary-level physical and sports education teachers regarding the teaching of thematic units (TU) in ISCED 1. We specifically examined variations in opinions based on teachers' educational backgrounds, seeking to gain insights into diverse perspectives and contribute to a comprehensive understanding of teaching practices in this context.Materials and Methods: The survey included teachers from the Prešov and Košice regions of Slovakia, totalling 341 participants, representing 8.17 % of the teacher population. Age distribution ranged from under 30 to over 50, with 63 men (18.48 %) and 278 women (81.52 %). Two groups were identified: the 1st group with a master's degree in elementary and preschool pedagogy (or equivalent), and the 2nd group with a full university education in a related field or a bachelor's degree. The survey, conducted in 2023, utilized both distributed and electronic formats. Statistical analysis involved percentages, the χ2 test, and correlation assessments for questions on thematic unit popularity and difficulty.Results: In the results section, it was found that manipulative, preparatory, and sports games was the most popular thematic units among teachers, chosen by more than half of the respondents from both surveyed groups. Conversely, psychomotor and health-oriented exercises were identified as the least popular TU. Basic movement skills were considered the least demanding TU in terms of teaching, while psychomotor and health-oriented exercises were perceived as the most demanding.Discussion: In terms of statistical significance, we have not noticed any significant differences when comparing responses of teachers with a degree in another field or a bachelor's degree in the field of elementary and preschool pedagogy and teachers with a master's degree in the field of elementary and preschool pedagogy. Notably, we identified a very strong direct correlation between the most demanding taught Thematic Unit (TU) and the least popular taught TU. Furthermore, our observations revealed a very strong indirect correlation between the most demanding and the least demanding taught TU.
