The quality of financial statements is the fundamental issue in terms of the reliability of the accounting conducted by those who prepare them. Since the beginning of the 21st century, and with the growing concerns regarding the data released in financial statements, the development of methods for testing the quality of financial reporting has been of great and growing importance. New methods designed for testing this quality are constantly being sought. It is also particularly important that in the event of significant changes in the scope of accounting and prepared financial statements, such as the introduction of IAS/IFRS, companies can be able to determine whether such integral changes influenced the quality of prepared statements and if so, to what extent. This paper is a description of the author's several years of research, completed in 2020, on quality changes in financial reporting in Poland resulting from the implementation of IAS/IFRS. The research was conducted on the entire population of companies listed on the Warsaw Stock Exchange (WSE) in the years 2005-2019 which shifted from Polish regulations to IAS/IFRS. The novelty of this article is the use of not only less known methods (other than earnings management) of quality measurement, but also the XGBoost method, which is unprecedented in other researchers.
