The latest Organization for Economic Co-operation and Development (OECD) report on education, the largest worldwide ranking regarding school systems that has ever been conducted, found that Asian countries have the best educational systems in the world. Furthermore, the report noted that if a state wants to boost its GDP, then it need to focus more on education. Singapore, Hong Kong, South Korea, Taiwan and Japan were ranked first, as the countries with the best educational systems in the world, while Ghana ranked last. Meanwhile, it appears Greece did not fair too well, since it ranked 40th on a global level and 29th among other European countries. “This is the first time we have a truly global scale of the quality of education,” said OECD education director Andreas Schleicher. The analysis is based on results of mathematics and physics tests in 76 countries. “The idea is to give more countries, rich and poor, access to comparing themselves against the world’s education leaders, to discover their relative strengths and weaknesses, and to see what the long-term economic gains from improved quality in schooling could be for them,” Schleicher added. Meanwhile, the OECD also conducted a study on the estimated growth of GDP in each country, on the condition that children attend school and receive basic education. “Poor policies and practices in education leave many countries in a permanent economic recession,” stressed the report. Education improvement has “long term economic benefits.” For example, if all children in Greece receive basic education, GDP is expected to increase to 285%.
