Polytechnic University of the Philippines Open University

The Polytechnic University of the Philippines Open University System is the nontraditional/distance studies unit of the Polytechnic University of the Philippines. It began with the offering of non-degree (technical-vocational) courses in 1970s and was formally established in 1990, making it the first open learning institution in the country. It is one of the only two open learning institutions in the Philippines recognized by the UNESCO Asia Pacific Knowledge Base on Open and Distance Learning.

The PUP Open University was established to provide education opportunities to individuals aspiring for higher education and improved qualifications but were unable to take advantage of traditional modes of education because of personal and professional obligations. It is also known as the "Pamantasang Bayan", literally translating to as "Nation's University" in Filipino.
