The article looks at a study done by the Educacion y Educadores research team at Universidad de La Sabana on the characterization and needs of teachers-administrators at elementary and secondary schools in Colombia , both public and private. The theoretical and methodological basis of the study and some of the results are summarized. Among its findings, the study showed teachers-administrators are trained in business theory, which they apply to education fairly easily, but with no in-depth analysis that is consistent with its objectives. Business contents have pervaded education policy and administrative practices, and have influenced the concept of the school, the actions of administrators and the use of business language. As a result, one sees less of a preponderance of theories nurtured by educational and pedagogic knowledge.
