The purpose of this study was to determine the causal factors for termination among Jewish day school principals in the United States, the rate of termination, and its effect on the schools. Ten hypotheses were designed for the study. The instruments used in the survey were two self-designed questionnaires, one for school principals and the other for board presidents. The population consisted entirely of the principals and board presidents of 328 Jewish Day Schools (233 principals and 114 board presidents responded). According to both principals and board presidents, the four most important reasons for principal termination included relations with the board, career and advancement, competency, and financial reasons. Although no single variable seemed to be primarily responsible, each factor contributed to the total picture in which executive termination could readily occur. It appears that those principals who do not ignore the political realities of their educational environment and who take political steps to solve educational problems will become an integral part of the school system.
