Researchers and theorists in the management and educational leadership fields have debated the importance of mission statements. This study investigated this issue within the context of American schools that are members of the Tri-Association (Mexico, Central America, Colombia, and the Caribbean). The results showed that about the same percentage of principals felt that mission statements differed and did not differ significantly from one school to the next. However, a considerable number of principals reported using their mission statements in many of the managerial and leadership tasks of their daily jobs.
