Introduction. The formation of the legal education system in the Chuvash Republic in the post-Soviet period is an important component of the history of the formation of Russian statehood and regional educational systems. Despite the presence of a significant array of publications on this topic, a comprehensive source and historiographical analysis necessary for further scientific research has not yet been conducted.The purpose of the study is to carry out a systematic analysis and classification of a set of sources, as well as historiographical works devoted to the process of formation and development of the legal training system in the Chuvash Republic in the post–Soviet period. Materials and methods. The work is based on the principles of historicism and scientific objectivity. General scientific (analysis, synthesis, systematization) and special historical (historical-genetic, comparative-historical, historical-typological) methods, as well as methods of source and historiographical analysis are applied. Results. For the first time, an extensive array of diverse sources on the topic (regulations, conference materials, periodicals, sources of personal origin) was introduced into scientific circulation and critically comprehended. The periodization of historiography was carried out, the key stages and vectors of research were identified. Discussion. For the first time, the classification and critical evaluation of the entire set of sources on the topic, including regulations, conference materials, periodicals and sources of personal origin, has been carried out. The periodization of historiography has been carried out, the stages of its development from description to analysis have been identified, and the circle of key authors and research centers has been identified. Both achievements of regional science and significant gaps have been identified, in particular, insufficient knowledge of the social history of education, career trajectories of graduates, as well as the lack of comparative studies with the experience of neighboring regions of the Volga region. Conclusion. The scientific novelty of the work is to create a holistic picture of the source and historiographical base of the topic, which forms the methodological foundation for subsequent research in the field of educational history, regional history and the history of law.
