This document discusses internal and formative assessment in medical education. It defines internal assessment as assessment done by teachers who have taught a subject, and notes its benefits include overcoming day-to-day variability and allowing for larger sampling of topics. Formative assessment is defined as assessment for learning that provides ongoing feedback to both teachers and students. The key elements of effective formative assessment are identifying learning goals, involving students in self-assessment, and providing timely feedback. The document provides examples of how to incorporate more formative assessment into an existing system focused on summative assessment and internal exams.
