The Latin American Center for Administration for Development (CLAD), in its Ibero-American Charter of Public Function (2003), emphasizes the critical need to professionalize public function and to have public servants with the appropriate skills for the exercise of public service. Indeed, the CLAD proposed that the first step is the professionalization of its bureaucratic elite, who must be technically prepared and motivated. In 2003, Chilean legislation (Law19.882) created the Senior Public Management System, which requires a meritocratic selection process for certain senior executive and intermediate manager positions, resulting in a three-year appointment. At the same time, it also maintained “(…) with regard to removal, the quality of employees of the exclusive confidence of the authority empowered to order their appointment” (Article 58, Law 19.882), allowing their removal at any time. Due to poor results, such as the early termination of a significant number of appointments, the system was modified in 2016 (Law 20.955). This chapter examines the contribution of the Senior Public Executive System (modified in 2016) to the professionalization of the Chilean bureaucratic elite and reduced bureaucratic turnover.
