School administrators develop, recommend, and carry out policy for school districts. The policy can have long lasting effect on students. Ideology and gender of the administrator can influence adoption and implementation of individual school's policy. A study consisting of quantitative and qualitative measures was utilized to determine the difference of opinion between male and female administrators through a survey about zero tolerance discipline policy. Missouri public high school principals were the focus of the study, each receiving the opportunity to participate in the survey via email. The results of this study are consistent with previous studies, but enhance the knowledge base with new evidence. Data analysis resulted in identification of gender preferred discipline methods related to zero-tolerance discipline policy in the areas of: (a) acceptability of zero-tolerance as a discipline policy, (b) academic outcome differences of students suspended more than, compared to less than, 90 days, (c) ability of the threat of suspension and expulsion to deter negative behavior, and (d) positive or negative lasting effects for zero tolerance on students.
