The most prominent change in teaching Croatian language according to curriculum reform happened in the 1st grade of primary school. The key document for planning the contents of learning and teaching used to be Croatian Teaching Plan and Programme which has been replaced by National Curriculum Framework. Croatian Teaching Plan and Programme was the document of programme planning where as National Curriculum Framework is the document of curriculum planning. National Curriculum Framework is the key programme of curriculum reform „School for Life― which has been frontally implemented in the 1st and 5th grade in all primary schools in the Republic of Croatia since school year 2019/2020. In National Curriculum Framework the emphasis is on teaching and learning outcomes, not on the contents of teaching and learning. The most important difference is that pupils in the 1st grade learn how to read and write only upper case and lower case printed letters where as before they used to learn handwritten letters as well. There are some other differences between the two documents which have been explained in this graduation paper. This graduation paper contains basic document features, its components, aim, evaluation, teaching and learning principles, outcomes and tasks. Further more, a research among 1st grade teachers in the Republic of Croatia was conducted. The aim of there search was to get in sight into what teachers think about programme and curriculum planning, evaluation methods and using ICT in teaching Croatian language.
