Schools need principals who have experienced the most current and compelling theories and practices of school leadership in terms of leading schools to success for each student. There is a considerable amount of research that proposes a definite link between the leadership abilities of a school leader and the impact such leadership has on student success (Darling-Hammond, LaPointe, Meyerson, & Orr, 2007; Heck & Hallinger, 2014; Marzano, Waters, & McNulty, 2005). School principals, like leaders in other fields, encounter differing levels of success, which can be influenced by the leadership abilities and ethical behaviors of the school principal. This quantitative study, which took place in a large metropolitan area of the Mid-Atlantic region of the United States, examines the relationship between the overall leadership abilities of school principals with their ethical leadership behaviors, as perceived by teachers. This study found a strong (and expected) relationship between the overall leadership abilities of school principals and ethical behaviors, as perceived by teachers. However, statistically significant differences were found among the perceptions in the areas of gender, ethnicity, experience, types of school (elementary, middle, high) and jurisdiction (public, private, religious).
