THE AUTHOR SUBMITS THAT PROBLEMS OF FINANCE AND STUDENT CAPACITY NECESSITATE INCREASED FLEXIBILITY IN SCHOOL PROGRAMS. A POSSIBLE SOLUTION IS PRESENTED--SCHEDULING THE SCHOOL YEAR ON A QUARTER SYSTEM (OR THE FLEXIBLE SYSTEM)--UNDER WHICH ONLY 75 PERCENT OF THE STUDENTS WOULD BE IN SCHOOL AT THE SAME TIME AND THE SCHOOL YEAR WOULD BE EXTENDED TO 11 MONTHS. THIS SYSTEM WOULD INCREASE TEACHER EFFECTIVENESS BY GIVING TEACHERS PROFESSIONAL WORK 11 MONTHS A YEAR AND SUBSTANTIALLY INCREASING THEIR SALARIES. SUCH A PROGRAM WOULD ALSO GIVE STUDENTS GREATER FLEXIBILITY IN PROGRAM PLANNING. ACCELERATED AND DECELERATED PROGRAMS COULD BE EFFECTED MORE EASILY. TWO POSSIBLE FLEXIBLE SYSTEMS ARE PROPOSED--(1) THE PUPIL ROTATION PLAN, AND (2) THE CONSTANT QUARTER PLAN, BOTH OF WHICH ARE DETAILED IN THE REPORT. (HW)
