What is the primary purpose of IEA assessments?

The primary purpose of IEA assessments is to evaluate and compare educational systems and learning outcomes across different countries. This involves gathering data on educational achievement, teaching methods, and curriculum effectiveness, which can provide insights into the varying educational practices globally. By analyzing such data, policymakers and educators can identify strengths and weaknesses in their own systems and learn from practices that lead to improved outcomes elsewhere. This comparative aspect is crucial for making informed decisions about education reform and policy development, as it highlights what works in diverse contexts and allows for an evidence-based approach to improving education systems worldwide.
