This study sought to evaluate the effectiveness of a two-quarter, extended orientation program for new, undecided students at the University of California, Irvine (UCI). The course was designed to assist students with the transition from high school to college and acquaint them with strategies to maximize their success at UCI. Of the 690 new, unaffiliated freshmen who entered UCI in fall quarter 1993, 24 enrolled in the extended orientation course for both quarters, 34 enrolled in fall only, 30 enrolled in the winter quarter, and 602 enrolled in neither quarter. The study found that, compared with other unaffiliated students who did not enroll in the extended orientation courses, those who enrolled for one or more quarters obtained significantly higher grade point averages (GPAs) and units completed by the end of spring quarter. Approximately 90 percent of students surveyed who expressed satisfaction with the course said that they would recommend it to other freshmen. (MDM)
