Pembimbing: competencies were defined and articulated in the National Education Standards (NES) and Ministerial Decrees 12/2007 and 13/2007. International research findings indicate that the quality of educational leadership has an impact on the quality of educational outcomes. For this reason, during the current Strategic Plan period, the Ministry of Education and Culture and the Ministry of Religious Affairs (MoRA) have placed significant emphasis on building the competency and capacity of principals and supervisors through the development and implementation of new approaches to recruitment, appraisal and Continuing Professional Development (CPD). These priorities were consistent with Presidential Instruction No. 1 of 2010 (INPRES), which focused on the empowerment of MoEC and MoRA school/madrasah principals and supervisors, through provision of professional development programs. MoEC and MoRA required baseline data about the current competency levels of principals and supervisors to inform and guide future CPD programs. This information has been collected through the implementation of ACDP 7 – Principal and Supervisor Competency Baseline Study.
