The development of a prototype computerized, criterion-referenced test of certain nonperformance musical behaviors for administration to entering students in music education at a state university was undertaken. After the formulation of statements of competencies to serve as conceptual bases for the formulation of test items, items were constructed for 12 subtests. Four subtests were selected for programming. The test was programmed sequentially for the IBM 1500 Instructional System. The students' score for each subtest was the number of items actually answered correctly plus the number of items for which a correct answer was assumed. The computerized test was administered to 32 undergraduate music education students. A parallel conventional version of the test was given to 28 other students, and a comparative analysis was made. The tests were not shown to be equivalent. Quantitative inadequacies may be explained by the discrepancies between estimated orders of item difficulty and the true orders of item difficulty for the particular students tested. From a qualitative standpoint, the computerized test performs adequately. With refinement, it could provide a convenient, rapid assessment of students in regard to certain expected nonperformance musical competencies. (Author/CK)
