The objective of this study is to evaluate the administrative infractions and the administrative disciplinary procedure applied to university professors in the Court of Honor of the National University of the Altiplano of Puno (UNA-Puno) during the periods 2022–2023. The following proposal was subsequently put forth: The objective of this study is threefold: first, to identify the administrative infractions committed by university professors; second, to identify the administrative disciplinary procedure applied in the Court of Honor; and third, to propose a guide that allows for the optimization of this procedure, ensuring transparency and efficiency in university disciplinary management.  The research adopted a mixed approach, incorporating the case study method, to analyze files and resolutions of teachers prosecuted for breach of duty, ethical faults, absences, and property damages. A meticulous examination of the documentary evidence was conducted, complemented by a systematic dogmatic analysis, both of which were carried out in accordance with the regulatory framework delineated by University Law No. 30220 and Law No. 27444 – General Administrative Procedure Law. The findings demonstrate that the classification of the infraction conditions the initiation of the disciplinary procedure and the severity of the sanction, thereby confirming the validity of the principle of proportionality. However, it is also evident that disciplinary procedures, although formally legitimate, generate perceptions of mistrust, institutional resistance, and weakening of the ethical culture, affecting both individual conduct and the collective academic climate. A proposed solution to address this issue is the creation of a guide to the disciplinary administrative procedure. The purpose of this guide is to standardize stages, deadlines, and criteria for assessing the offense. The creation of this guide would guarantee speed, motivation, and predictability in decisions. As a result, institutional legitimacy would be strengthened, and a university culture based on ethics and respect for fundamental rights would be promoted.  In conclusion, it is evident that administrative infractions and disciplinary proceedings in the UNA-Puno University Court of Honor not only condition the severity of the sanctions but also affect the perception and behavior of the teachers involved. Despite a decline in cases between 2022 and 2023, ongoing tensions persist, associated with the proportionality, expediency, transparency, and legitimacy of the procedure.
