This report compares the characteristics of Santa Ana College (SAC) students enrolled in the fall 1966 semester with those of SAC students enrolled in fall 1976. Although the average age of SAC students has increased by only one year (from 26.9 to 27.8), the distribution of ages has radically changed, from modes of 18 and 22-25 to a single mode of 22-25. In 1976, 55% of SAC students were classified as "continuing," as compared with 29.8% in 1966. Growth has also been realized in the percentage of students returning to SAC without enrolling in classes elsewhere. In 1976, more students attended classes on a part-time basis and during both day and evening. The percentage of students enrolled full-time has decreased from 34.7% to 27.3%. Female enrollment has increased by 7%, while male enrollment has decreased by 6%. Average scores on the skills-oriented COOP-Expression test dropped 10% since 1966, while average COOP-Total scores declined 5% in the same period. However, average scores earned by students on aptitude tests have increased slightly. The overall GPA for SAC students has increased by 0.57 points, as a result of an increase in the number of "A's" and "W's" issued and a decrease in the number of other grades given. (DC)
