Section 16-26-3
Elementary and high school may be placed under same principal.
Subject to the rules and regulations of the State Board of Education, where economy of organization and administration seems to justify it, county boards of education may place the elementary, junior and senior high schools of any district or districts under one and the same principal, or may use any other plan of organization approved by the county board of education.
