Education serves as a critical tool for developing an individual's knowledge, mindset, behavior, attitudes, values, and morality, aiming to produce good, competent, and efficient citizens. Educational services provided by various organizations involved in the education sector must prioritize and support these aspects. This includes offering guidance, advice, and educational planning for learners. Effective preparation and planning for personnel are essential, along with understanding the needs of multiple stakeholders to align with the demands of employers and the labor market. The establishment of Occupational Standards and Professional Qualifications serves as a validation of individuals’ skills, knowledge, and competencies required for specific occupations. This process relies on principles aligned with international standards, applicable to both educational institutions and workplaces. Workplace-based training, for example, is essential and necessary for human resource development. It equips personnel with competencies that match the actual needs of employers by offering hands-on training, skill development, and the ability to effectively operate machinery, tools, and equipment utilized in workplaces. In the context of educational institutions, school administrators—who serve as managers in educational areas or institutions—play a pivotal role. These individuals, as representatives of institutions or associations overseeing the educational administration profession, bear responsibilities as heads of institutions. They are also required to adhere to defined standards in their professional practices.
