Introductory course of reading and writing is a basic component of learning the native language in Croatian primary education system. During the school year 2005/2006, Croatian elementary schools used seven different spelling books. In order to provide explanation in terms of their scientific justification and to examine the need to standardize some elements of reading and writing, analysis of those spelling books showed that due to their differences and the it is necessary to standardize the specific stages of reading and writing.. Conclusion was that it is necessary to standardize the specific stages of reading and writing. Faculty of Teaching Education in University of Rijeka conducted a research among the students about their attitudes towards implementation of the standard school letters for initial Croatinan language reading and writing. The results showed that the majority of students believe that the new school letters are more complex than those which they were taught and mastered. Nevertheless, students considerd the time allotted for teaching the new school letters within the University course Methodology of Croatian language was adequate and provided sufficient training for writing the new letters and because of that most of the students felt qualified to teach reading and writing, especially the fourth year of college. It turned out that the third year was the one that most commonly uses new school letters. This supports the fact that the learning outcomes of the third year University course Methodology of Croatian language is structured so that it enforces the implementation and learning of the new school letters, while the other study grups applied the letters but not such extent.
