The purpose of this study was to determine if implementing an honor code would diminish academic dishonesty at Tampa Catholic High School. Quantitative survey instruments were administered twice, in August 2009 and in January 2010, to measure the reaction of student and faculty participants to the introduction of an honor code. Survey responses indicated that there was a shift in behaviors towards increased academic honesty. Comparison of the first semester data over the last two years showed a 38% decrease in the number of students disciplined for academic dishonesty. Future directions to advance the school's culture of academic integrity include the organization of an Honor Council, student participation in the establishment of academic integrity policies, and faculty professional development.
