International education benchmarks affect local standards by providing frameworks for comparison and improvement. These benchmarks establish performance criteria that schools and systems can strive to meet, promoting accountability and quality assurance. They enable educators to identify gaps in student performance and assess the effectiveness of teaching practices. Furthermore, benchmarks guide curriculum development and policy-making by offering evidence-based insights into successful educational strategies from around the world. By aligning with international standards, local education systems can enhance their credibility and effectiveness.
