THE REPORT IS CONFINED TO THE QUESTION OF THE PREFERABLE CALENDAR FOR THE UNIVERSITY OF CALIFORNIA AND CALIFORNIA STATE COLLEGES, AND IS NOT SPECIFICALLY CONCERNED WITH THE UNDERLYING REASONS FOR INSTITUTION OF YEAR-ROUND OPERATIONS, SUCH AS POSSIBLE LONG-TERM SAVINGS IN COSTS AND BENEFITS TO STUDENTS. THE FOUR-QUARTER CALENDAR IS SUGGESTED OVER THE TRIMESTER BECAUSE OF ITS GREATER FLEXIBILITY AND BETTER ARTICULATION WITH OTHER EDUCATIONAL INSTITUTIONS. FOR GRADUATES OF JUNIOR COLLEGES, THE PROBLEMS OF ARTICULATION ARE ABOUT THE SAME AS FOR GRADUATES OF HIGH SCHOOLS. PRESIDENTS OF JUNIOR COLLEGES INDICATE A 4-QUARTER CALENDAR WOULD BEST ARTICULATE WITH THEIR PRESENT SYSTEM. BEST RESULTS, THOUGH, WILL BE OBTAINED IF THE UNIVERSITY SYSTEM, THE STATE COLLEGES, AND THE PUBLIC JUNIOR COLLEGES HAVE THE SAME SYSTEM WIDE BASIC CALENDAR. WITH THE NUMBER OF GOVERNING BOARDS IN CHARGE OF THE PUBLIC JUNIOR COLLEGES, IT IS NOT FEASIBLE TO OBTAIN WITH ANY DEGREE OF IMMEDIACY A UNIFIED ACTION ON YEAR-ROUND OPERATION. MOREOVER, WITH THE GREAT RANGE IN FULL-TIME ENROLLMENTS AMONG THE JUNIOR COLLEGES, STATEWIDE ACTIONS SHOULD EXEMPT THOSE COLLEGES WITH MINIMAL ENROLLMENT. (HS)
