This paper presents findings of a study that analyzed the extent of burnout among Mississippi high school principals. Specifically, it identified the level of burnout among Mississippi high school principals, the relationship between certain demographic variables and burnout, and the relationship between burnout and personality type. The level of burnout among high school principals in Mississippi schools as a total group as well as within specific demographic variables of age, sex, race, years of experience, school enrollment, level of education, and intent to remain in the job was measured by three subscales of the Maslach Burnout Inventory (MBI)--emotional exhaustion, depersonalization, and personal accomplishment. Data were collected through a survey comprised of the MBI, part 1 of the Leadership/Personality Compatibility Inventory (L/PCI), and demographic survey. The survey was mailed to 127 Mississippi high school principals in October 1993; 87 usable responses were received. Findings indicate that the principals had low to moderate levels of burnout as measured by the subscales of emotional exhaustion and depersonalization. Data also show that respondents experienced a high degree of personal accomplishment in their work. However, because a sizeable number of the principals experienced moderate or high levels of emotional exhaustion and depersonalization in their roles, concern is warranted. Finally, principals with sympathetic personalities had significantly higher levels of emotional exhaustion than did those with bold or technical personalities. Four tables are included.
