In order to determine whether there were compelling reasons for Schenectady County Community College (SCCC) to change its quarter calendar, and which calendar would be most appropriate to the college and most responsive to the problems that made the change seem desirable, previous calendar change studies were reviewed and administrators of colleges that had made calendar changes were consulted. The types of calendars initially considered were: (1) semester; (2) early semester (the fall semester begins in August and ends before Christmas); (3) trimester (three semesters over 12 months); (4) quarter; and (5) four-one-four (division into four months-one month-four months). Only the quarter and semester systems were considered feasible for SCCC. Issues related to calendar changes include curriculum conversion and related concerns of credit hours and flexibility; comparative academic success rates in various calendars; enrollment patterns as reflected in student program change and the effect on part-time students; and transferability of courses to other colleges. Significant calendar change studies were conducted at Kent State, Cleveland State, University of Akron, Miami University of Ohio, Chabot College, and College of the Redwoods. Advantages and disadvantages of each calendar plan have been outlined by the "Handbook on Undergraduate Curriculum," and are summarized in this report. Results of the study included a recommendation to remain with the quarter system. (MB)
