The job of administering schools has become increasingly complex because of the many societal changes occasioning new demands on the school. Principals are held accountable for administration of their schools, and their effectiveness depends largely on their ability to respond appropriately to the many changing internal and external demands, and to maintain the stability and cohesiveness necessary to the achievement of established goals.

Schools cannot improve without people working together... None of us no matter what our position, has the answer to the complex problems we face. The more people work together the more we have the possibility of better understanding those complex problems and acting on them in an atmosphere of trust and mutual respect. (Liebermann 1986,6)
