In spring 1975, students attending evening classes only comprised 17 percent of the total enrollment of the community colleges of Hawaii; day-only students comprised 71 percent, and students attending both day and evening classes comprised 12 percent. In all three groups, the majority are male liberal arts majors who were on campus last semester and who are U.S. citizens with Hawaii residency status. The evening-only group differs from the other groups in the following ways: (1) proportionately more have not declared majors; (2) fewer are vocational students; (3) proportionately more were not on campus last semester; (4) over twice as many attend part-time; (5) more are married; and (6) most are older by five to eight years. Compared to the fall 1972 evening-only group, the spring 1975 evening-only group is more than twice as large and is comprised of more males, more "continuing" students, more married students, more full-time students, more vocational students, and more who have declared majors. In both spring 1975 and fall 1972, 41 percent of the evening-only students are liberal arts majors. Data is represented in tables which indicate figures for the entire system and for each of the six Hawaii community colleges. (DC)
