Abstract: The historical aspects of the emergence of corporate governance and the regulatory features of the OECD Guidelines on corporate governance for state-owned enterprises are considered.

Methodological approaches to assessing organizational effectiveness are outlined, in particular target, systemic, functional, intraorganizational, competitive and compositional concepts, as well as the concept of balance of interests. The criterial base of such methods for assessing the level of corporate governance as the Davis Global Advisors Inc. Index, Creighton-Miller and Warman Corporate Governance Risk Index, Standard & Poor’s Corporate Governance Level, Deminor Corporate Governance Rating (DR), Moody’s Index, Corporate Governance Indicator (IIS), methodology for assessing corporate governance by T. Momot and M. Kadnichansky is analyzed.

It was revealed that the main attention in the most common indices for measuring corporate governance is paid to such elements as the structure of the board of directors and the supervisory board; ownership structure; shareholder influence and exercise of voting rights; financial transparency; protection of property rights. These aspects are considered in the context of their relationship with the processes of privatization and reform of state property. The main requirements of the OECD Guidelines for the board of directors of enterprises with state participation are described.. It is proposed to supplement the methods for assessing the level of corporate governance taking into account ESG issues.
