Introduction: Due to conflicts of interest, agency problems, dishonest practices and lack of social responsibility, norms, standards and regulations have been designed worldwide to protect the interests of each stakeholder, as a consequence of a critical situation that affects the relationship between the principal and the agent. Objective: This research aims to analyze the corporate governance practices of Chilean companies that are part of IPSA. Materials and methods: Company statements on the level of compliance with NCG 341 and NCG 385 were taken as reference, both promulgated by the SVS, for which a compliance ranking has been developed by category, company and practice, giving way to the determination of the effect that this change of regulatory framework caused in the level of compliance with the regulations. Results: Among some of the results, we can mention the significant change in the position of AntarChile S. A. and SalfaCorp S. A. Conclusion: The generalized low performance is due to the rigor of the new standard, causing a compliance decrease from 72% to 39%
