What is a primary benefit of cross-national studies conducted by IEA?

The primary benefit of cross-national studies conducted by IEA is that they allow for the examination of educational effectiveness across different contexts. This type of research facilitates comparisons between various education systems, helping to identify what practices are effective in different countries or regions. By analyzing the performance of students and systems in diverse cultural, economic, and social contexts, researchers can gain valuable insights into the factors that contribute to educational success or challenges. This understanding can inform policymakers and educators about strategies that may work in their own settings, fostering a more informed approach to education reform and improvement globally.
