Recent developments in software and hardware capabilities have made possible the combination of the Music Achievement Test (MAT) series and the PLATO music programs as a new delivery system. Initial reactions to the PLATO administration of digital to analog (D to A) testing in music have been positive; the immediate feedback available by computer, plus the individual pacing of the student are good reasons for this early success. The mode of test presentation remains a major question for extensive further study. If computer administered testing is standardized in the future, the chore of item analysis and test validation can be an easy matter, and it will be possible to have a continuous updating of norms.
