The purpose of this book is to present a basic yet comprehensive treatment of assessment methods for use by health professions educators. While there are many excellent textbooks in psychometric theory and its application to large-scale standardized testing programs and many educational measurement and assessment books designed for elementary and secondary teachers and graduate students in education and psychology, none of these books is entirely appropriate for the specialized educational and assessment requirements of the health professions. Such books lack essential topics of critical interest to health professions educators and may contain many chapters that are of little or no interest to those engaged in education in the health professions
