Assessment in Health Professions Education The health professions, i.e., persons engaged in teaching, research, administra- tion, and/or testing of students and professionals in medicine, dentistry, nursing, pharmacy, and other allied health fields, have never had a comprehensive text devoted specifically to their assessment needs. Assessment in Health Professions Education is the first comprehensive text written specifically for this audience. It presents assessment fundamentals and their theoretical underpinnings, and covers specific assessment methods. Although scholarly and evidence-based, the book is accessible to non- specialists. • This is the first text to provide comprehensive coverage of assessment in the health professions. It can serve as a basic textbook in introductory and intermediate assessment and testing courses, and as a reference book for graduate students and professionals. • Although evidence-based, the writing is keyed to consumers of measure- ment topics and data rather than to specialists. Principles are presented at the intuitive level without statistical derivations. • Validity evidence is used as an organizing theme. It is presented early (Chapter 2) and referred to throughout.
