Time is a key intangible resource in the school.  The limitation of a definite amount of time is identified by many principals and teachers as one of the most serious constraints they face in attempting to meet the challenges presented by the managerial arena.  Clear job specifications for staff, negotiated through sympathetic and reciprocal process of appraisal, which relate to the aims and objectives of the school and priorities, identified can be useful instruments in achieving more effective utilization of the total bank of time available to and utilized by all the staff in the schools.Campbell, Corbally and Nystrand (1971) compared time and wages as written by Fredrick Taylor that: All productive effort should be measured by accurate time study and a standard time established for all work done in the shop (school). Wages should be proportioned to output and their rates based on the standard determined by time study.

Peters, Routledge and Kegan (2004) stated that economic use of the time includes in common use of heads-time, staff time, and even more important pupils time.  The head teacher should have complete control over the time of all employed in the school like when he controls time in the classroom through a time table.  Staff time is to a large extent taken care of by the timetable. Jacobson, Reavis and Logsdon (1954)emphasizes that before schools open, the principal must have an opening schedule, plan, and execute the year‘s work.  Problems of opening of school, the way in which the school opens will have a profound effect on student teacher and patrons.  For proper management of time, the ideal is to have the new term open as though schools were being resumed from a weekend recess.
