ANTICIPATING A CHANGE FROM A SEMESTER TO A QUARTER SYSTEM OF INSTRUCTION, CUYAHOGA COMMUNITY COLLEGE SURVEYED 357 COLLEGES AND UNIVERSITIES (EACH WITH 3,000 OR MORE ENROLLED) TO DETERMINE THE TYPE OF INSTRUCTIONAL CALENDARS BEING USED, THE METHOD OF SCHEDULING EVENING CLASSES, THE NUMBER OF MEETINGS PER WEEK, AND THE LENGTH OF CLASS SESSIONS. RESPONSES FROM 310 OF THE INSTITUTIONS (87 PERCENT), INDICATED THAT (1) 73 PERCENT OF THE 4-YEAR COLLEGES FOLLOWED SEMESTER CALENDARS, 21 PERCENT FOLLOWED QUARTER CALENDARS, 5 PERCENT WERE ON TRIMESTERS, AND 1 PERCENT USED OTHER TYPES OF CALENDARS, (2) 84 PERCENT OF THE 2-YEAR COLLEGES FOLLOWED THE SEMESTER PLAN, 9 PERCENT FOLLOWED THE QUARTER CALENDAR, AND 7 PERCENT THE TRIMESTER OR "OTHER" CALENDAR SYSTEMS, (3) 62 PERCENT OF THE 4-YEAR COLLEGES SCHEDULED EVENING CLASSES ONCE PER WEEK, 33 PERCENT TWICE PER WEEK, AND 4 PERCENT THREE TIMES PER WEEK, (4) 36 OF THE 310 RESPONDENTS INDICATED THAT THEY HAD CHANGED THE NUMBER OF WEEKLY MEETINGS OF REGULARLY SCHEDULED EVENING CLASSES SINCE 1960, AND (5) CHANGES IN TYPES OF CALENDARS DID NOT ADVERSELY AFFECT ENROLLMENT. CONCLUSIONS DRAWN FROM THE STUDY, PERTINENT TABLES, AND RECOMMENDATIONS FOR THE CUYAHOGA PROGRAM WERE INCLUDED. (DG)
