Overview
Dean is a title employed in academic administrations such as colleges or universities for a person with significant authority over a specific academic unit, over a specific area of concern, or both. In the United States and Canada, deans are usually university professors who serve as the heads of a university's constituent colleges and schools. Deans are common in private preparatory schools, and occasionally found in middle schools and high schools as well.
Origin
A "dean" (Latin: decanus) was originally the head of a group of ten soldiers or monks. Eventually an ecclesiastical dean became the head of a group of canons or other religious groups.
When the universities grew out of the cathedral schools and monastic schools, the title of dean was used for officials with various administrative duties.
