A study of the effect of a principal's termination on the school was derived from the results of the research of Causal Factors of Termination among Jewish day school principals in the United States during the period 1980-85. 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. Seventy percent of the participants responded to the questionnaire. A statistical analysis system was used on the survey data, cross-tabulation, and anova. Twelve variables were found to be related and affected the schools negatively. Short periods of tenure and rapid changes in the principal's position tended to reduce the effectiveness of the office and delayed the development of desirable outcomes for the school. Implementation of strategies for increasing retention is the responsibility of both the school board and the principal. (8 references) (Author/KM)
