Despite the fact that test development is a growth industry that cuts across all levels of education and all the professions, there has never been a comprehensive, research-oriented handbook to which everyone (developers and consumers) can turn for guidance. That is the mission of this book. "The Handbook of Test Development" brings together well-known scholars and test-development practitioners to present chapters on all aspects of test development. Each chapter contributor is not only a recognized expert with an academic and research background in their designated topic, each one has also had hands-on experience in various aspects of test development. This 32-chapter volume is organized into six sections: foundations, content, item development, test design, test production and administration, and post-test activities. The handbook provides extensive treatment of such important but unrecognized topics as contracting for testing services, item banking, designing tests for small testing program, and writing technical reports.
