The document describes the development of objectives and presents objectives formulated by music educators, lay individuals, and the National Assessment of Educational Progress (NAEP) staff in 1973. Objectives from the first music assessment were reappraised, reviewed, and revised to include greater breadth of application, greater emphasis on the affective domain, greater variety of music styles, and the use of music training background to provide context. Recommendations concerning assessment content and administration included that objectives be based on aurally presented materials and administered by persons who have had music training. Depth of coverage should also be increased with age level. The objectives are presented in five categories, which focus on the students' involvement in performing, creating, and responding to music. Category I measures how the student values music as an important realm of human experience, including responsiveness; acquaintance with music from various nations, cultures, periods, and ethnic groups; importance of music personally; and ability to make and support aesthetic judgments. Category II focuses on the ability to perform, while Category III measures the ability to create musical expression. Category IV measures the ability to identify the elements and expressive controls of music, such as rhythm, pitch, tone, and musical terms. Category V focuses on the ability to identify and classify music historically and culturally.
