Document Number: 2956Using Web-Based Testing for Large-Scale Assessment - The focus of this paper is on the use of computer-based tests that are tailored ("adapted") to each studentís own level of proficiency. The authors believe that current trends toward greater use of high-stakes tests and the increasing presence of technology in the classroom will lead assessment in this direction. Furthermore, they argue that although web-based testing holds promise for improving the way achievement is measured, a number of factors may limit its usefulness or potentially lead to undesirable outcomes. This paper was written to help stimulate discussion and research that will address the many issues raised by a shift toward web-based testing. (Laura S. Hamilton, Stephen P.
