This guide for college teachers, written from a British perspective, focuses on economic and efficient practices for assessing students. The guide groups various practices under 10 major strategies: (1) decide whose interests assessment is serving; (2) avoid over-sampling the course; (3) avoid over-questioning; (4) avoid over-reading student work; (5) avoid over-commenting on student work; (6) avoid over-grading work; (7) refine current policies and find ways of using present methods better; (8) consider alternative approaches to assessment policy and practice; (9) consult original sources for how-to-do-it details. Each strategy is discussed in a separate section which begins by presenting some general rules and then suggests particular assessment tasks in light of identified key factors. Each section also describes and explains various practices and practical applications with citations from the literature that describe the use or development of that practice. All the specific practices were chosen either because the editors were personally familiar with them or because the practices have been addressed in the educational literature. Practices were chosen because they potentially offer greater economy and efficiency in assessment and because of their educational value. Contains 113 references. (JB)
