The world around us is changing rapidly day by day, and the development of computer science has enabled the creation of information and communication technology. Nowadays, every individual needs knowledge of digital literacy to perform everyday tasks on the computer and various computer systems. In 2018, during the education reform curriculum for the subject of Informatics for primary and secondary schools in the Republic of Croatia was issued. As the education reform took place in the Republic of Croatia, so in the Czech Republic in 2021 the Ministry of Education, Youth and Sports adopted a revised Framework Education Program for Primary Education. The purpose of the audit is to adapt educational content to the needs and dynamics of the 21st century. Namely, the idea of the diploma thesis was to find out what primary school computer science teachers from the Republic of Croatia and the Czech Republic think about the mentioned curricula.Thesis Comparison of attitudes of IT teachers on the curriculum of Informatics in primary education in Croatia and the Czech Republic is based on a survey of attitudes of IT teachers in primary schools in the Republic of Croatia and the Czech Republic. The main idea of this paper is to analyze the educational systems of the two European countries, define the expected outcomes and basic competencies of students and compare the advantages and disadvantages of the curricula of Informatics from both countries. The results of the research show that IT teachers from both countries are equally satisfied with the curriculum of the subject Informatics and want to be further educated about it. Furthermore, research shows that age does not affect the time of preparation for a subject, and that the competencies of teachers will not vary depending on their work experience. Gender also does not affect better coping in the curriculum of the subject of Informatics.
