* The 1987 Philippine Constitution: Article XIV, Section 1, mandates the State to establish, maintain, and support a complete, adequate, and integrated system of education. Preschool education falls under this umbrella.
* Basic Education Act of 2013 (Republic Act No. 10533): This act, also known as the K to 12 Law, fundamentally reshaped the Philippine education system. While it focuses on the primary and secondary levels, it implicitly acknowledges and integrates preschool as a foundational stage, impacting curriculum and potentially funding. It integrates Kindergarten into the basic education cycle.
* Education Act of 1982 (Batas Pambansa Blg. 232): Although largely superseded by later legislation, this act established a framework for education that earlier informed the development of preschool programs. Some aspects might still be relevant in terms of overall educational policy and principles.
* Department of Education (DepEd) Orders, Memoranda, and Circulars: These administrative issuances provide specific guidelines, curriculum standards, and implementation details for preschool programs, clarifying and operationalizing the broader legal framework laid out in the aforementioned laws. They are crucial for daily practice in preschool institutions.
* Local Government Code of 1991 (Republic Act No. 7160): This gives local government units (LGUs) a role in providing and supporting basic services, including education. LGUs may play a significant part in funding, establishing, and managing preschool programs within their jurisdiction.
It's important to note that the legal landscape is constantly evolving. New laws, amendments, and administrative orders continually shape the legal basis for preschool education in the Philippines. Therefore, relying on the most recent official publications from DepEd and the Office of the President is crucial for the most up-to-date and accurate information.
