Educators in that department may report to that head who in turn reports to a higher level administration, such as a school or college in a university, or directly to the main administration, such as the principal or head of a school. Educational institutions using the departmental model often provide traditional education. This is a traditional form of organization with an emphasis on traditional classroom forms and organizations that has been the dominant organizing model of high or secondary schools, colleges, and universities since the late 19th and early 20th century.[3][4] This is reflected in the design of educational facilities with separate faculty buildings on a campus, or in a wing or cluster of standard classrooms or laboratories in a high school (e.g. science labs, vocational shops).[5]
