Abstract
In recent decades, international organizations have been actively conducting large-scale education quality assessments, such as PISA, aimed at identifying and improving educational achievements. These assessments play an important role in the analysis of educational systems in different countries, providing data for comparative analysis and identifying successful practices. One of the key goals is to use this data to improve domestic education policies and improve their quality. Despite universal recommendations, testing results usually depend on the specifics of educational systems. Auditing the effectiveness of secondary education allows countries to adjust their educational strategies and focus on examples of countries with high results. The article also highlights the difficulties associated with borrowing successful practices and introducing standards into national educational systems.
