The major purpose of this literature review is to determine what is known about a) prevailing patterns of interaction between leaders and other adults in public schools and b) conditions under which specific patterns of behavior of leaders are connected with variations in the behavior of other people in the school. A second objective is to find out what patterns of behavior make a difference in the performance of others and under what circumstances such connections between leader behavior and the behavior of others occurs. The literature is reviewed in terms of a network of forces, or of independent conditioning and dependent variables, with student learning considered as the major output or dependent variable. A heuristic model of this network is diagrammed and discussed in the introduction. The literature review is organized into sections on the role of the leader, leader behaviors and characteristics which have impact on others, and conditions affecting leader behavior and its consequences.
