Students of organizations know that the descriptive value of an organizational chart is limited. The flow of power and control within a school system is often a result of informal associations rather than the product of strict definitions of formal line and staff relationships. Such charts often have limited value. They depict control, or what we might better call authority, only in legal or formal terms. There are actually several authority structures in a school system-the formal and legal delegation of authority to an office by reason of its placement in the organization; the informal and extra-legal delegation of power and control to an individual above and beyond the formal limitations of his office; and the collegial or professional authority structure, which will be discussed later in this presentation. Officers at the top of the formal organization have more legal authority than those who follow, consider, for example, the broad discretionary powers granted a board of education or superintendent.
