Book excerpt: The Alliance for Clinical Education (ACE) is proud to announce its newest text, the Handbook on Medical Student Evaluation and Assessment. This comprehensive book derives from some chapters in the indispensable fourth edition of the Guidebook for Clerkship Directors, but expands upon those chapters and contains critical new information about milestones, professionalism, and program evaluation. It is useful not only for clerkship directors, but also for preclinical educators, teachers of electives and subinternships, the dean's office, the student affairs office, residency and fellowship program directors, and anyone who teaches, advises, or mentors medical students. It discusses all aspects of assessing learners, with well‐referenced presentations starting from basic definitions, progressing through various assessment methods, and including reviews of the legal aspects of assessments.
