Integrating sound assessment and instruction has been a long-sought goal in education. Recent advances in educational measurement, cognitive science, and artificial intelligence have placed this goal within our reach. Intelligent systems may be improved by leveraging assessment information that is gathered from various sources (e.g., summative and formative), thus providing a viable approach toward accomplishing the aforementioned goal. This chapter analyzes the role of assessment in intelligent systems, summarizes the characteristics of successfully deployed intelligent systems, and describes an evidence-based approach to incorporating valid and reliable assessments into enhanced intelligent systems. 1 After July 25, 2007, my contact information will be: Valerie J.
