This paper considers uses of technology in educational assessment from the perspective of innovation and support for teaching and learning. It examines assessment cases drawn from contexts that include large-scale testing programs as well as classroom-based programs, and attempts that have been made to harness the power of technology to provide rich, authentic tasks that elicit aspects of integrated knowledge, critical thinking, and problem solving. These aspects of cognition are seldom well addressed by traditional testing programs using paper and pencil or computer technologies. The paper also gives consideration to strategies for developing balanced, multilevel assessment systems that involve articulating relationships among curriculum-embedded, benchmark, and summative assessments that operate across classroom, district, state, national, and international levels. It discusses the multiple roles for technology in an assessment-based information system in light of the decision support needed from the multiple actors who operate across levels of the education system. The paper concludes with a consideration of the current state of the field as well as the potential for technology to help launch a new era of integrated, learning centered assessment systems.
