An evaluation of PISA 2015 achievements of OECD countries within income distribution and education expenditures

Abstract

The purpose of this study was to determine the relationships between student achievements, income distribution and expenditure on educational institutions in the member countries of Organization for Economic Co-operation and Development (OECD). In the study, the level of student achievements of the member countries was expressed by Programme for International Student Assessment (PISA) 2015 scores for providing updated data. In the study, income inequality was determined to be one of the variables having impact on the PISA achievements of the students. However, it was considered that some countries, the income inequalities of which were under OECD average, were also successful in PISA 2015. In this regard, it was also searched for an answer to how OECD member countries distribute educational resources, how their public and private expenditure ratios on education were, how their annual expenditure for per student was, and how efficient they use these expenditures on education. It was concluded in the study that the student achievements of OECD member countries were much more associated with fair and efficient use of educational resources, rather than the amount of these resources
