School counselors work closely with students and are often the first point of contact regarding traumatic experiences. It is generally understood that exposure to other individuals' trauma may lead to a reduction in compassion satisfaction and an increase in secondary traumatic stress, while long-term exposure may result in professional burnout. This study examined the role of school counselors' (N = 240) own adverse childhood experiences (ACEs) as related to compassion satisfaction, secondary traumatic stress, and burnout. Results indicated that 50% of the professional school counselors in this convenience sample had personal histories of four or more ACEs, which is significantly higher than the general public and passes the threshold for significant risk. Results indicated that the ACEs of school counselors in the present study, as well as some demographic variables, significantly correlated with rates of compassion satisfaction, secondary traumatic stress, and burnout.
