In this sense, it is argued that the deficient legislative technique used in the design of this figure of Provisional Administration in school matter, causes that the actors of the school system do not adequately understand its true nature and public purpose.En el presente trabajo se analizan las principales normas de la Ley N°20.529 (en adelante, Ley SAC), que regulan la figura del Administrador Provisional de establecimientos subvencionados o que reciban aportes del Estado.
