This booklet offers a census of course offerings and enrollments in art, music, dance, theater, and literature in junior and senior high schools in Illinois. It is part of a series of reports surveying statewide basic curriculum data. Data were collected in 1977 and reflect the 1976-1977 school year. All public secondary schools in Illinois were surveyed and responses were received from 95% of all high schools and 97% of junior high schools. The objective was to produce a source of data on secondary school curriculum and enrollments. Information is presented in narrative and tabular form. In addition to information on course offerings, information is presented on school size and community type (central city, suburb, independent city, or rural). Highlights of the report are that almost all Illinois junior high school students take at least one course in art and music; virtually all high school arts courses are elective; rural high school students take more music courses than students in other regions; central city students enroll heavily in both high school art and music, male/female enrollments are relatively equal in junior high arts courses, females are more likely than males to take art and music courses in high school, and faculty cutbacks in the arts may substantially affect arts instruction. The document concludes with an appendix listing art, music, literature, theater, and dance courses offered in Illinois. (Author/DB)
