The document discusses quality assurance systems for education. Over the last 15 years, more than 60 countries have established their own national quality assurance systems for education in response to initiatives by organizations like the OECD and IMHE. This has led to more public assessments and international comparisons of education institutions. Evaluation mechanisms and good teaching practices are important for quality assurance. Quality teaching initiatives can take a top-down or bottom-up approach, depending on whether they are instituted by institutional leadership or teachers. Properly evaluating quality teaching is challenging, but institutions are making progress by combining professional development and research.
