School administrators are faced with the responsibility of disciplining students for misconduct on the school bus. Some bus drivers frequently send discipline referrals to the administration, whereas others seldom do. This study attempts to identify certain personality traits of bus drivers that contribute to good student behaviors. Bus drivers from rural Missouri school districts who drove regular school routes were given the Global 5 Personality Trait Test. Building principals from these rural school districts gathered bus discipline referrals for the first semester of the 2008-2009 school year. The research design is quantitative causal-comparative in nature, while the data was collected and analyzed with the use of multiple t-tests and the Pearson r. No significant differences between the personality traits of drivers with numerous discipline referrals were found compared to the drivers with minimal bus discipline referrals.
