This collection presents educational assessment research from Latin America, adding to a relatively small but growing body of research considering educational assessment and evaluation issues in this large region. The predominance of Chile reflects its early highly centralized education system, and the fact that it adopted national testing before other Latin American countries. It was also an early participant in international assessment programmes. Other countries have followed the trend of implementing national testing, and to a lesser extent participating in international surveys. The complementary development of technical expertise in quantitative research methods has enabled extensive analysis of the large data sets generated by these testing and assessment programmes. Taken together, the evidence reported provides a means not only of reviewing educational quality issues in Latin America, but also of facilitating comparisons that allow the context specificity of equivalent research conducted in western developed countries to be considered. The chapters in this book were originally published as a special issue of Assessment in Education: Principles, Policy and Practice.

From the United States to the United Kingdom and from China to India, growing inequality has led to social discontent and the emergence of populist parties, also contributing to economic crises. We urgently need a better understanding of the roots and costs of these income gaps. The Costs of Inequality draws on the experience of Latin America, one of the most unequal regions of the world, to demonstrate how inequality has hampered economic growth, contributed to a lack of good jobs, weakened democracy, and led to social divisions and mistrust. In turn, low growth, exclusionary politics, violence and social mistrust have reinforced inequality, generating various vicious circles. Latin America thus provides a disturbing image of what the future may hold in other countries if we do not act quickly. It also provides some useful lessons on how to fight income concentration and build more equitable societies.

This edited volume presents a systematic analysis of conceptual, methodological and applied aspects related to the validation of educational tests used in Latin American countries. Inspired by international standards on educational measurement and evaluation, this book illustrates efforts that have been made in several countries to validate different types of educational assessments, including student learning assessments, measurements of non-cognitive aspects in students, teacher evaluations, and tests for certification and selection. It gathers the experience of validity studies from the main international assessments in Latin America (PISA, TIMSS, ERCE, and ICCS). Additionally, it shows the challenges that must be taken into account when evaluations are used to compare countries, groups or trends of achievement over time. The book builds on the premise that measurements in the educational field should not be used if there are no studies that support the validity of the interpretation of their scores, or the use made of such tests. It shows that, despite the recognition given to validity, relatively few educational measurement assessments have accumulated enough evidence to support their interpretation and use. In doing so, this volume increases awareness about the relevance of validity, especially when assessments are key component of educational policies.

To improve their education systems, countries around the world have increasingly initiated national largescale assessment programs or participated in international or regional large-scale assessment studies for the first time. Well-constructed large-scale assessments can provide credible information on student achievement levels, which, in turn, can promote better resource allocation to schools, stronger education service delivery, and improved learning outcomes. The World Bank developed this Primer on Large-Scale Assessments of Educational Achievement as a firststop resource for those wanting to understand how to design, administer, analyze, and use the results from these assessments of student achievement. The book addresses frequently asked questions from people working on large-scale assessment projects and those interested in making informed decisions about them. Each chapter introduces a stage in the assessment process and offers advice, guidelines, and country examples. This book also reports on emerging trends in large-scale assessment and provides updated information on regional and international large-scale assessment programs. DIRK HASTEDT, Executive Director of the International Association for the Evaluation of Educational Achievement (IEA) “A special feature of the publication is that it not only gives an overview of technical specifications, but also includes examples from around the world on how countries are conducting large-scale assessments, what they found, and how the results were used. With this perspective, the Primer on Large-Scale Assessments of Educational Achievement is an excellent and easy-to-read publication to get a comprehensive overview of large-scale assessments and how and why they are conducted.†? SILVIA MONTOYA, Director of UNESCO Institute for Statistics (UNESCO UIS) “If you are responsible for learning assessment in a country and are searching for a comprehensive, yet readable, guide on large-scale assessment, this is your book. Extremely well structured and written, this primer is easy to follow, and makes points clearly and concisely. It is an excellent resource that explores the steps for a good large-scale assessment with examples from all international large-scale assessment programs.†? ANDREAS SCHLEICHER, Director for the Directorate of Education and Skills and Special Advisor on Education Policy to the Organization for Economic Cooperation and Development’s (OECD) Secretary- General “Many countries have joined international educational assessments to benchmark quality, equity, and efficiency in their education systems. But what does it take to design and implement those efforts well and to draw value from this to help students learn better, teachers teach better, and schools to work more effectively? This Primer on Large-Scale Assessments of Educational Achievement helps policy makers and their technical teams to find answers to these questions.†? ANDREI VOLKOV, Director of the Institute for Public Strategy, Moscow School of Management SKOLKOVO “In 2008, when the Russia Education Aid for Development (READ) Program was launched, we determined its main goal as the improvement of the quality of basic education. Today, the READ Program keeps setting trends as the largest Russian initiative promoting educational assessment. Approaches developed within the READ Program, from building institutional and expert capacity to influencing educational reforms, have proven their efficacy in many countries. The Primer on Large-Scale Assessments of Educational Achievement brings together in a practical format the best experience and case studies in conducting assessments under the READ Program. An especially important feature of the book is an integrated capacity building component, which makes it a practical tutorial ready for use in different cultural contexts. Through this book, we hope that our collective experience gathered during READ will be widely shared, bringing us closer to achievement of the Sustainable Development Goal on education.†? evelopment Goal on Education.†?
