This paper reviews the history of technology and testing. The role and functions of computers in education have become more varied, from drill and practice to simple tutorials toWebQuests. However, one important aspect of teaching for which the computer is ideally suited, achievement testing, is often overlooked. While it is not difficult to envision computers administering and scoring tests, there is also learning that occurs when tests are administered by a computer. Advantages and disadvantages of computer-based testing are also examined. Finally Type II applications are explored.
