With the drastic increase in the amount and types of data due to advancements in information and communication technology, the significance of data literacy has become more prominent. This study examined the elements of data literacy included in the achievement standards of the revised 2022 national curriculum, investigating how data literacy elements are reflected across various subjects such as Korean literature, mathematics, social studies, science, and practical arts. Analyzing 600 achievement standards related to data literacy, the study found that data interpretation and data-based inquiry were the main elements identified, with the application of data varying across subjects. The Korean literature focused on data communication, while mathematics stressed statistical problem-solving. An increasing trend in the ratio of data interpretation and databased inquiry was observed with higher grade levels, although it was challenging to clearly discern the learning hierarchy of data literacy elements. Through this analysis, the study suggests the necessity of systematic guidance on data literacy education in the curriculum and a deeper understanding of how data literacy elements vary by subject. This research provides foundational data on integrating data literacy into the curriculum and offers insights into how students can be supported in developing the ability to extract information from data and utilize it to solve problems.
