In this book, 37 international academics illustrate how authentic assessment is an effective measure of intellectual achievement as it requires the demonstration of deep understanding and complex problem solving through the performance of exemplary tasks. By exploring the concept of authentic assessment in both tertiary and school education, the authors in these chapters argue that authentic assessment is not only the measurement of significant intellectual accomplishments but also an important pedagogical structure. Authentic assessment is a concept more closely defined as an umbrella term that seeks to immerse learners in environments where they can gain highly practical and lifelong learning skills. Authentic assessment has been on the educational agenda for a number of years and keeps being a powerful tool for assessing students’ 21st century competencies in the context of global educational reforms.
