The Clark County Fire Department (CCFD) is located in Las Vegas, Nevada, one of the fastest growing counties in the nation. This phenomenal growth has challenged CCFD to formulate a strategy to deal with issues concerning training, diversity, and recruitment. To address this problem, an aggregate personality profile was developed for firefighter, engineer, captain, and battalion chief using the Keirsey Temperament Sorter II. The purpose was to determine the magnitude of similarities and differences within each group. Using descriptive research techniques, the study indicated a significant trend in personality temperament, SJ-Guardian, and personality types, ISTJ and ESTJ. Further research is recommended to develop guidelines using personality profiling to evaluate training, diversity, and recruiting efforts. A comparative study needs to be conducted to develop a comprehensive demographic profile utilizing additional demographic variables.
