The paper explores the possibilities for developing reading comprehension by a pupil in primary education in the Slovak Republic. The need for scientific research into developing reading literacy in Slovakia, with its educational implications, is growing as a result of the unsatisfactory state of the current educational context. In this paper, we present an educational strategy focused on the development of comprehension of an informational text in primary school pupils. The strategy is based on the outcomes of previous research on the effectiveness of developing text comprehension on the basis of parallel stimulation of linguistic and cognitive processes. The presented stimulation programme offers a model for school education and for teachers how to proceed with the systematic development of comprehension of an informational text. At the same time, we offer the presented strategy for developing the reading literacy of a pupil for comparison with educational strategies in different countries.
