Professional school counselors are faced with the task of implementing a comprehensive school counseling program that supports the academic, social-emotional, and college and career development of all students they serve. While implementing such with additional demands, school counselors may encounter ethical dilemmas. A non-experimental survey research design using multiple regression analysis was used to examine the relationship between ethical decision-making (EDM) of professional school counselors (N=102), global belief in a just world (GBJW), social justice advocacy, and training. A total of 102 professional school counselors responded to the survey. Results suggest a statistically significant negative relationship between EDM and GBJW and a statistically significant positive relationship between coursework and EDM. Implications and suggestions for future research are discussed.
