The purpose of the study is to use cluster analysis to analyze survey data in order to identify the features of students' digital identity. The general methodology of the study is presented, according to which preliminary data processing was carried out in order to prepare them for subsequent analysis. The paper uses hierarchical clustering using Ward's algorithm to analyze behavioral factors affecting the formation of students' digital identity. The study used survey data collected among 324 students from three regional universities of the Republic of Kazakhstan. The content of the questions includes digital activity and interaction of students in the online space, as well as questions about their academic, research and social activities.
